Radical cyclisation of dienes and enynes using TolSO2SePh
摘要:
Reaction of a number of 1,6-diene or enyne systems with TolSO2SePh, under free radical conditions, results in selenosulphonylation with concommitant C-C bond formation, to give cyclised alkyl or vinyl sulphones containing the synthetically useful phenylselenyl functionality.

Reaction of diphenylphosphine with suitable 1,6-diene or enyne systems, under free radical conditions, results in addition of a phosphorus-centred radical and cyclisation to form substituted phosphines and vinyl phosphines respectively.
