摘要
从N,N ' -二烯戊基-1,2-苯基二氨基配体RC6H3[(CH2But)]2中，通过还原消除法制备了两个稳定而活泼的双(氨基)硅烯的代表1a和1b，并用核磁共振波谱和1a x射线晶体学对其进行了表征。硅烯[图略](CH2But)]2C6H3-1,2-R (R = H 1a或4-Me 1b)很容易与乙烷或梅尔氧化加成。
Synthesis, structures and reactions of new thermally stable silylenes.
Two representatives 1a and 1b of a new series of stable but reactive bis(amino)silylenes, derived from the N,N′-dineopentyl-1,2-phenylenediamido ligand RC6H3[(CH2But)]2, have been prepared by reductive elimination from RC6H3[[graphic omitted]SiCl2 and characterised by NMR spectroscopy and for 1a X-ray crystallography; the silyienes [graphic omitted](CH2But)]2C6H3-1,2-R (R = H 1a or 4-Me 1b) readily undergo oxidative addition with EtOH or Mel.
