Direct Formation of Organomanganese Tosylates and Mesylates and Some Cross-Coupling Reactions... 

We reported that Mn does, in fact, undergo oxidative addition to alkyl and benzylic tosylates and mesylates under mild conditions to yield the corresponding organomanganese tosylates and mesylates in excellent yields. To our knowledge, this is the first example of organomanganese tosylates and mesylates prepared via direct oxidative addition of manganese metal or by any metathesis approach.

Benzylic Manganese Halides, Sulfonates, and Phosphates 329 Table 8.12 Preparation of organomanganese tosylates and their coupling reaction. 

As shown in Table 8.12, the oxidative addition to alkyl tosylates and coupling reactions of organomanganese tosylates were also investigated. The oxidative addition was easily completed by simple treatment of Mn with the alkyl tosylates at rt in THE...
