새로운 니켈(Ⅱ) 화합물, 비스(트리메틸실릴메틸)1,2-(비스디페닐포스피노) 에탄니켈(Ⅱ)(1)이 디클로로-1,2-비스(디페닐포스피노)에탄니켈(Ⅱ)와 트리메틸실릴메틸리튬의 반응으로부터 합성되었다. 화합물 1은 질소하, 상온에서 안정하다. 화합물 1은 열분해하여 환원성짝지음 생성물, 1,2-비스(트리메틸실릴)에탄을 생성한다. 화합물 1은 상온에서 일산화탄소 및 산소와, 그리고 80℃에서 1,2-비스(디페닐포스피노)에탄과 반응하여 역시 1,2-비스(트리메틸실릴)에탄을 생성한다.

A new nickel(Ⅱ) compound, Ni(CH2SiMe3)2((C6H5)2PCH2CH2P(C6H5)2), 1, has been prepared by the reaction of NiCl2((C6H5)2PCH2CH2P(C6H5)2) with Me3SiCH2Li. The compound, 1, is stable under nitrogen at room temperature both in solution and in the solid state. Thermal decomposition of 1 in solution or in the solid produces the reductive coupling product, Me3SiCH2CH2SiMe3 which is also afforded by the reactions of 1 with CO and O2 at room temperature, and with (C6H5)2PCH2CH2P(C6H5)2 at 80℃.
