Treatment of triarylstannyl-bis(3,4,5-trimethylpyrazol-1-yl)methane, Ar3SnCH(3,4,5-Me3Pz)2 (Ar = phenyl or p-tolyl), with W(CO)5THF results in the oxidative addition of the tin−carbon(sp3) bond to the tungsten(0) center to yield the heterodinuclear complexes CH(3,4,5-Me3Pz)2(CO)3W−SnAr3, in which four-membered metallacycles are found and bis(3,4,5-trimethylpyrazol-1-yl)methide acts as a tridentate monoanionic
用W(CO)处理三芳基锡烷基双(3,4,5-三甲基吡唑-1-基)甲烷Ar 3 SnCH(3,4,5-Me 3 Pz)2(Ar =苯基或对甲苯基)5 THF导致锡-碳(sp 3)键氧化键合到钨(0)中心,从而生成杂双核络合物CH(3,4,5-Me 3 Pz)2(CO)3 W-SnAr 3,其中四元metallacycles被发现和双(3,4,5-三甲基吡啶-1-基)甲基化物作为一个三齿单阴离子κ 3 - [N,C,N]螯合配体。
