Abstract: By the reaction of PO(NCS)3 or (PhO)2PONCS with 2-hydroxytetrahydropyran, 2-isothiocyanatotetrahydropyran was formed in a good yield. This, after addition of amines or alkoxides afforded expected thioureas and thiocarbamates, respectively. After addition of substituted anilines, only monosubstituted arylthioureas were isolated from the reaction mixture. Addition of phenol or 2-naphthol gave corresponding 2-tetrahydropyranylaryl ethers. By using of mesitylnitrile oxide, the obtained thioureas and thiocarbamates were converted into the corresponding ureas and carbamates, respectively.
