A radical intermediate is generated when methylidenecyclopentane ( 1 ) is isomerized by SO 2 into 1‐methylcyclopentene ( 3 ) through the formation of a polysulfone polymer (PS), which first abstracts a hydrogen atom from the alkene. The allyl radical intermediate 2 abstracts a hydrogen atom from another alkene molecule 1 , to yield the isomerized alkene and regenerating the allyl radical. Polysulfones are organic catalysts.
