Concept introduction:
Attack of the nucleophile, triphenyl phosphine, on the epoxide obtained from a trans alkene, opens up the ring. Free rotation is possible in C–C bonds. The rotation of the C–C single bond and subsequent removal of triphenylphospheneoxide will yield the cis product.
To propose:
A mechanism for the conversion of the epoxide (obtained by treating a trans alkene with peracids) into cis alkene by treatment with triphenylphosphine.
