✦ Synopsis
The reductive dehydration of ketones to form olefins has been accomplished in a variety of ways with generally only moderate success. 3 Among the more recent and better ways to make this conversion are those involving hydroboration

Starting from the diaminodiphosphanes 1 and 21Za1 we have now succeeded in synthesizing the tetraphosphabicyclobutane system (4a, b) by PP-coupling to give the tetraphosphane 3 and subsequent cyclizing amine-elimination.

Mannich reaction between dimethyl (methylene) ammonium chloride and a silyl enol ether gives a regiochemical result opposite to that obtained from the derived lithium enolate and the same salt.
