Reactions of Allylsilanes with Iminium Salts: Ene Reactions with Inverse Electron Demand
摘要:
The N,N-dialkylmethyleneammonium hexachloroantimonates 1-SbCl6- react with allyltrimethylsilane (2a) in dichloromethane to give the alkylideneammonium ions 3 and 3' via ene reactions with inverse electron demand, where the allyltrimethylsilane (2a) behaves as enophile. Under the same conditions (2-methylallyl)trimethylsilane (2b) undergoes ordinary ene reactions with iminium ions, with the allylsilane 2b acting as the ene component. The different course of the ene reactions is explained by the varied steric strain in the pericyclic transition states 14-18. S(E)2' products, which are the main products under more nucleophilic reaction conditions, have only been detected in trace amounts.

bisphenoxyiminato complexes based on highlysubstituted p- and m-terphenyl backbones were synthesized, and the corresponding atropisomers were isolated. In the presence of a phosphine scavenger, Ni(COD)2, the phosphine-ligated syn-dinickel complexes copolymerized α-olefins and ethylene in the presence of amines to afford 0.2-1.3% α-olefin incorporation and copolymerized amino olefins and ethylene with a similar
