Organomolybdenum and Organotungsten Reagents, II. — On the Carbonyl‐Olefinating μ‐Methylene Complex from Mo 2 Cl 10 and Four Equivalents of Methyllithium Mo 2 Cl 10 reacts at — 70°C with 4 equivalents of methyllithium to give a methylated thermolabile molybdenum complex. At higher temperatures it forms a thermolabile carbonyl‐olefinating reagent which according to NMR data is the μ‐CH 2 complex Cl 3 Mo(μ‐CH 2 ) 2 MoCl 3 ( 2 ). Reactions of 2 with aldehydes, ketones, azomethines, and epoxides are described.
