Notes:
Silylphosphines R3SiPR′2 add on the C=N group of aldimines yielding phosphinylated silylamines of the structure . Hydrolysis of these adducts leads to the corresponding substituted aminomethyl-phosphines.In the reaction between α-diimines and silylphosphines or silyldiphosphines R2Si(PR′2)2 the acyclic 1/1 and ½ addition compounds have been characterized. The adduct 1/1 obtained by the action of diethyl-hydrodimethylsilyl-phosphine on di-tert-butylimino-ethane undergoes in the presence of Wilkinson's catalyst, (Ph3P)3RhCl, an intramolecular Si-H/C=N cyclisation leading to a phosphinylated siladiazolidine.Silylphosphines add to N-acylimines in 1,4 position to form phosphinylated siloxyimines. The methanolysis of the latter derivatives is an novel method of preparation of phosphinylated amides.Silyl- and germylphosphines react on the C=N groupement of cetimines. The hydrolysis of the adducts (N-metallated enamines) leads to C-phosphinylated imines.
