Reactions of Becker-type phosphaalkenes 5a-e with triorganotin hydrides 1a,b proceed through 1,2-addition to furnish the stannylphosphanes 7a-j. Analogous use of the diorganotin dihydrides 11 and 14 gives rise to the hydridostannylphosphanes 12 and 15. The product 16 of a double addition can also be isolated from the reaction of dimethyltin dihydride 14 with the phosphaalkene 5a.
