Thiolysis of alkyltin alkoxides and oxides

Dibutyltin diethoxide was found to interchange its ethoxy groups readily with thiols forming Bu2Sn(SR)2. These thiolates can also be synthesized by refluxing the crude Bu2SnO with thiols in the presence of benzene. Molecular weight determinations showed them monomeric. Some of these higher homologues can be prepared by displacement reactions with higher thiols. The reaction of dipropanethiodibutylstannane with ethanol is very slow even in the presence of catalyst

A study of the tetra-alkylthiostannanes, Sn(SR)<SUB>4</SUB>

The synthesis of tetra-alkylthiostannanes, Sn(SR)4, (where R = C2H5, n-C2H7, iso-C2H7, n-C4H9, iso-C4H9 tert-C4H9, n-CP12H25, C6H5 and C6H5 &#183; CH2) through an alternative convenient route employing ammonia as a proton acceptor is described. Stannic isopropoxide also exchanges its isopropoxy groups with thiols. Thiolysis reactions of Sn(SEt)4 and Sn(SPr)4 with higher thiols have been investigated for the first time

Butylgermanethiolates

A number of new, volatile butylgermanethiolates Bu2Ge(SR)2 and Bu3Ge(SR) (R = C2H5, C3H7, iso-C3H7, C4H9, iso-C4H9, tert-C4H9, n-C12H25, CH2C6H5 and C6H5) have been synthesized by the reaction of the corresponding chlorogermane with thiol in the presence of a proton acceptor. The action of thiol on di- and tributylgermanium oxides could be pushed to completion in the presence of catalyst. A few typical displacement reactions of these derivatives with thiol as well as ethanol have been studied. Infrared spectra of these butylgermanethiolates have been examined
