Direct generation of thiomethylmanganese reagents and their reactions withelectrophiles - Organometallic ate compounds in organic synthesis. 35.

Trialkylmanganese(II) ate reagents, "R3MnLi", reacted with iodomethyl sulfi des to produce thiomethylmanganese reagents, where the manganate serves as a reductant, not an alkylation agent. In this reductive metalation of halid es with alkylmanganese ate complexes, the relationship between oxidative ad dition and the metal-halogen exchange reaction was revealed. A wide variety of modifications of "thiomethylmanganese reagents" thus generated in react ivity could be made.
