Abstract: Thirteen new trans-cyclothiophosphorylthiourea derivatives,R1R2NC(S) NHR3(R1=H,alkyl;R2=alkyl, substituted plienyl;R3=4-phenyl-5,5-dimethyl-2-sulfo-1,3,2-dioxaphosplioranyl),were synthesized by the addition reaction of frans-2-isothiocyano-4-plienyl-5,5-dimethyl-2-sulfo-1,3,2-dioxaphosphorinane to various amines respectively and their structure were confirmed by means of elemental analysis,1HNMR and IR. The biological activities of all new compounds were tedsted preliminarily and the results indicate that some compounds showed fungicidal activity and plant-growth reguiarity activity. In addition,the stereochemistry of the reaction between 2-chloro-4-phenyl-5,5-dimethyl-2-sulfo-1,3,2-dioxaphosphorinane and potassium thiocyanate was reported for the first time.
