Palladium-Catalyzed Synthesis of α-Diimines from Triarylbismuthines and Isocyanides

In this study, we report a highly selective coupling reaction between triarylbismuthines and isocyanides using palladium diacetate as the catalyst, affording α-diimines, with the formation of three C-C bonds. Among several aryl sources (Ar-YLn: Y = B, Sn, Pb, Sb, Bi, I), only triarylbismuthines successfully undergo coupling with isocyanides to selectively afford α-diimines. The coupling reaction exhibits the advantages of high atom economy and convenient operation, with no need for any additive.

A CONVENIENT AND NOVEL ONE-POT SYNTHESIS OF 3-OXO-P-1,5,3-DIAZAPHOSPHEPINES AND 3-THIOXO-P-1,5,3-DIAZAPHOSPHEPINES

In a convenient one-pot sequence, treatment of benzil-dibenzylimine with sodium in dry tetrahydrofuran followed by addition of phosphorodichloridate and phosphorothiodichloridate yields 3-oxo-P-1,5,3-diazaphosphepines and 3-thioxo-P-1,5,3-diazaphosphepines, respectively. Key Words: Benzyl dibenzylimine; phosphorodichloridate; phosphorothiodichloridate; diazaphosphepines; spectral studies.
