Article abstract of DOI:10.1039/DT9810001738

It is shown that platinacyclobutanes derived from methylcyclopropane exist as a mixture of isomers with partial structures PtCH2CHMeCH2 and PtCH2CH2CHMe, and that these isomers interconvert easily.In some cases decomposition of these platinacyclobutanes gives ylide complexes L>, e.g.L = 2-methylpyridine, while in other cases but-1-ene complexes , e.g.L = CD3CN, are formed.In both cases the products are formed selectively from the least stable isomer of the platinacyclobutane.At higher temperatures or on photolysis, platinacyclobutane complexes such as decompose to give but-1-ene, 2-methylpropene, propene, and ethylene and the relative yields depend on the experimental conditions.Possible mechanisms are discussed.
