Direct coupling of aryl halides and alkyllithium compounds by palladium catalysis — ScienceDaily

Palladium catalysts help synthesize key chemicals for many industries. However, direct reaction of two basic reagents, aryl halides and alkyllithium compounds, remains a challenge. Now, a team of scientists have found that a catalyst containing YPhos-type ligands can mediate this reaction even at room temperature. This discovery may contribute to the development of more sustainable processes in the chemical industry, the authors write in the journal Angewandte Chemie.

Palladium-catalyzed chemical processes are very useful. Palladium catalysts help to couple simple carbon-containing compounds to form more complicated chemical structures. However, they have yet failed to couple two common reagents in chemical synthesis, aryl halides and alkyllithium compounds. Among the aryl halides, aryl chlorides are common synthesis reagents that react variably during palladium-catalyzed reactions to produce side products.

For coupling reactions with aryl halides and alkyllithium compounds, chemists usually take “detours” by adding intermediate synthesis steps. Unfortunately, every extra synthesis step

Measurements in thorium-229 take a step towards the direct laser excitation of an atomic nucleus in this unique isotope — ScienceDaily

Nuclear clocks could make our time measurement even more accurate than atomic clocks. The key to this lies in thorium-229, an atomic nucleus whose lowest excited state has very low energy. A research team from the Kirchhoff Institute for Physics at the University of Heidelberg, TU Wien, Johannes Gutenberg University Mainz (JGU), the Helmholtz Institute Mainz (HIM), and GSI Helmholtzzentrum in Darmstadt has now succeeded in measuring this low energy. Using an extremely accurate detector, it was possible to detect the tiny temperature increase due to the energy released during the de-excitation of the atomic nucleus. This brings the realization of a nuclear clock a big step closer.

In radioactive decay, atomic nuclei spontaneously re-arrange, eject some part of their building blocks, and transform into a nucleus of a different atom. In this process, the new “daughter atom” usually has internally stored energy that is released in the form of

Emails: Palantir blames Morgan Stanley for ‘blemished’ direct listing

  • In two emails sent internally this weekend, Palantir Technologies blamed Morgan Stanley for a “failure” that left some employee and alumni shareholders unable to sell their shares when the company made its public debut last Wednesday.
  • The problem stemmed from a glitch with Morgan Stanley’s trading platform Shareworks.
  • In an unsigned email sent late in the evening Sunday, Palantir said it had heard from Morgan Stanley that the bank was in a “war room” all weekend working to determine which shareholders were owed compensation. 
  • A spokesperson for Shareworks at Morgan Stanley said the issue was a “slowness” that “may have resulted in delayed logins into our system.”

Facebook Integrates Messenger Chat With Instagram Direct Messages

KEY POINTS

  • Facebook announced that it is integrating Messenger’s features into Instagram’s direct messages
  • The integration will make it easier for users to communicate across apps
  • The integration also brings a slew of features to Instagram

Facebook has announced that it is integrating the Messenger experience into Instagram direct messages, allowing users to enjoy the features of the messaging platform in the primarily photo-sharing app.

In a blog, Instagram’s Adam Mosseri and Messenger’s Stan Chudnovsky said the integration brings “the best Messenger features to Instagram,” allowing the latter’s users to stay connected with their non-Instagram-using family and friends.

Basically, Instagram and Messenger users will be able to message each other without having to download the other app.

The respective apps’ heads said that about 100 billion messages are sent each day via Facebook’s family of apps, which includes both Instagram and Messenger. About one out of three users, however, sometimes

Palantir officially begins trading through a direct listing

  • Shares of the big data company Palantir began trading on Wednesday via a direct listing.
  • The New York Stock Exchange established a reference price of $7.25 per share, valuing the company at about $16 billion ahead of its official debut.
  • Palantir has yet to become profitable, raising questions from investors.
  • Palantir also has faced criticism from activists for its work with Immigration and Customs Enforcement, which the company has acknowledged poses a risk to its business — partially because yielding to the criticism might endanger its business with government clients.
  • Visit Business Insider’s homepage for more stories.

Palantir, the secretive and often-controversial big data company founded by Peter Thiel, made its public markets debut on Wednesday with a splash, as investors bid up shares and gave the company a roughly $19 billion market capitalization.
