The reaction of - and trimethylammonium iodides (3a and 3c) with n-butyllithium gives N-- and N-dimethylamines (5a and 5b), respectively.A mixture of 5a and 5b is obtained from the reaction of trimethylammonium iodide (3b).Use of lithium diisopropylamide in place of n-butyllithium gives the corresponding 1,1-bis(trimethylelemento)ethylenes (8a, 8b, and 8c) as the main products.
SYNTHESE UND REAKTIONSVERHALTEN VON (DIALKYLAMINOMETHYL)CHLORSILANEN UND -STANNANEN

(Dialkylaminomethyl)chlorosilanes have been obtained by the reaction of trichlorosilane with bis(dimethylamino)methane.The corresponding stannanes have been prepared by the addition of methyleneimmonium halides to SnCl2.In the silicon compounds a covalent Si-CH2-N= bond is observed, while the tin compounds have ionic structures.Reactions of the new compounds are described.

Deprotonation of benzyldimethylammonium halides (10) with sodium amide or n-butyllithium afforded silylated ylide intermediates 11, which were rearranged into N,N-dimethyl-2-benzylamines (13) accompanied by the formation of Sommelet-Hauser and Stevens rearrangement products (12 and 22).The ylide formation by the cleavage of carbon-silicon bonds also is discussed in the reaction of 10 with sodium amide and lithium aluminum hydride.
