Description:
AbstractThe reaction of the dimeric bis(germylene) [Ge{3,5‐(CF3)2pz}2]2 (2) with protic molybdenum hydride [Mo(H)Cp(CO)3] yielded two different products. In diethyl ether the divalent germylene readily inserts into the Mo–H σ‐bond and the product of the oxidative addition, [Ge(H){Mo}(pz)2] (4) (with pz = 3,5‐disubstituted pyrazole, 3,5‐(CF3)2pz; {Mo} = [MoCp(CO)3]), was isolated featuring a germanium(IV) hydride moiety. In toluene an interesting “cascade” reaction takes place furnishing a bis‐metal substituted digermane [{Mo}(H)(pz)Ge–Ge(pz)2{Mo}]. Although the detailed mechanism of the reaction remains the subject of speculation it seems likely that a germylene, [GeII(pz){Mo}], inserts into the germanium(IV) hydrogen bond of [Ge(H){Mo}(pz)2] under formation of a germanium‐germanium bond, which is a rare reaction behaviour.
