Jack Teixeira, 21, a Massachusetts Air National Guard member, was arrested by the FBI yesterday in connection with the leaked intelligence reports, Attorney General Merrick Garland announced. Teixeira will appear in a Boston court today, according to the U.S. … 網頁These results established the so-called "first generation" of Buchwald–Hartwig catalyst systems. The following years saw development of more sophisticated phosphine ligands that allowed extension to a larger variety of amines and aryl groups. Aryl iodides, chlorides, and triflates eventually became suitable substrates, and reactions run with weaker bases at …
