[MoR(η3‐C3H5)3], R = Alkyl: Alkylmolybdenum Complexes with Agostic C-H ⇀ Mo Bond

Abstract
A dramatic high‐field shift of an 1H‐NMR signal characterizes the agostic Mo↼HC interaction in the isopropylmolybdenum complex 2. The bright yellow compound is accessible in 65% yield by reaction of the binuclear molybdenum complex 1 with isopropylmagnesium chloride at −78°C in ether. equation image
