Abstract: S-Alkyl thiophosphoro (-phosphono-)chloridates 4 were prepared by the isomer-ization/chlorination reaction of O,O-dialkyl thiophosphates(-phosphonates)3 with phospho-rus oxychloride- The isomerization/chlorination of 3 containing bulkier Rand R1 groups re-quire higher reaction temperatures and Ionger reaction time.4 reacted with 2, 6-dichloro-4-substituted phenols to give 26 new target compounds 6, which were tested in vitro against many fungi such as P.Zeae, P.Piricola, R.Solani, A- Solani and D.Arachidicala, etc.The bioassay results show they have some fungicidal activity.

Key words: Isomerization, Chlorination, Thiophosphates, Fungicidal activity
