The reactions of trimethyltinpentacarbonylmanganese with tetrafluoroethylene, trifluoroethylene, chlorotrifluoroethylene, and ethylene are described. Only with tetrafluoroethylene is an adduct, namely, (CH₃)₃SnCF₂CF₂Mn(CO)₅, obtained, although trimethyltin fluoride and fluorocarbon-carbonylmanganese products are also formed. With trifluoroethylene and chlorotrifluoroethylene, trimethyltin halides and fluorovinylpentacarbonylmanganese compounds are produced, although in the latter case perfluoroacryloylpentacarbonylmanganese, CF₂=CFCOMn(CO)₅, is a major product. Ethylene does not cleave the Sn-Mn bond, but rather displaces carbon monoxide to form (CH₃)₃SnMn(CO)₄(π-C₂H ₄). The spectroscopic properties of the new compounds are discussed.
