Abstract

A new nickel(II) compound, $Ni(CH_2SiMe_3)_2((C_6H_5)_2PCH_2CH_2P(C_6H_5)_2)$, 1, has been prepared by the reaction of $NiCl_2((C_6H_5)_2PCH_2CH_2P(C_6H_5)_2)$ with $Me_3SiCH_2Li$. 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, $Me_3SiCH_2CH_2SiMe_3$ which is also afforded by the reactions of 1 with CO and $O_2$ at room temperature, and with $(C_6H_5)_2PCH_2CH_2P(C_6H_5)_2$ at 80${\circ}$C.

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${\circ}$C에서 1,2-비스(디페닐포스피노)에탄과 반응하여 역시 1,2-비스(트리메틸실릴)에탄을 생성한다.
