Abstract The synthesis, physical, chemical and spectroscopic properties of eight different types of phosphinous-, phosphinic- and thiophosphinic amides are reported. It is shown that the 31P-chem. shifts of tertiary amides are at lower magnetic field than that of secondary amides. As an exception, in the bis(tertiary butyl) series this trend is reversed.
Rhodium(III)-Catalyzed Direct Coupling of Arylphosphine Derivatives with Heterobicyclic Alkenes: A Concise Route to Biarylphosphines and Dibenzophosphole Derivatives
The redox-neutral direct coupling of arylphosphine oxides with heterobicyclic alkenes proceeds smoothly under rhodium(III) catalysis involving hydroarylation followed by dehydrative aromatization to form biarylphosphine oxides. Related phenylphosphinic and phenylphosphonic esters as well as phenylphosphine sulfides also undergo ortho-arylative coupling. Furthermore, phenylphosphinothioic amides can

Tris(dialkylamino)-arsines (I), -stibines (II), and -bismuthines (III) react with sulfurdioxide to give the corresponding tetraalkylsulfurous diamides and the corresponding metal oxides or polymers containing the metals. The reactivity of these metal amides in view of the fastness of the initial reactions follows the order III>II>I, however, the yields decrease in the order I>II>III. Tris(dialkylamino)phosphines
A novel nucleophilicsubstitutionreaction at the nitrogen of arylsulfonamides by means of phosphide anions has been described. This reaction allows for the efficient transformation of arylsulfonamides into synthetically valuable phosphamides, amines, and a variety of protected amines.

In the reaction of trans-2,4-disubstituted azetidine, trans-2, 5-disubstituted pyrrolidine, or trans-2,6-disubstituted piperidine with diphenylthiophosphinic chloride or diphenylselenophosphinic chloride in acetonitrile in the presence of potassium carbonate at room temperature, an unexpected carbon dioxide insertion produced carbamic diphenylthiophosphinic or diphenylselenophosphinic anhydride in
