Abstract Reaction of β-triorganosilylethylammonium iodides with n-butyllithium in a HMPA/ether mixture at− 15 to− 20 C gave the corresponding α-triorganosilylalkylamines which were produced by 1, 4-anionic rearrangement of organosilyl groups from carbon to carbon in β-triorganosilylethylammonium ylides. Small amounts of the Hofmann elimination products, triorganovinylsilane and N, N-dialkyl-2-trimethylsilylethylamines, were also ...
