Phosphacycle

WebA small ring phosphacycle (phosphetane) catalyzes the synthesis of unsymmetrical hydrazines by cross-selective intermolecular NN reductive coupling of nitroarenes and anilines in the presence of a hydrosilane as the terminal reductant. The reaction offers good chemoselectivity and functional group tolerance. Webisonitrile adds to 1Dipp giving a 4-membered phosphacycle. In contrast to 1, the phosphaketene derived from the electrophilic diazaphospholidine-4,5-dione is unstable and reacts with a second molecule of Na [PCO(dioxane) x]toafford a 1,3,4-oxadiphospholonide derivative.
