Some of tin(ll) alkoxides and phenoxides, containing functional group which was of use to prevent the association of tin-tin or tin-oxygen bond, have been prepared by the reaction of tin(ll) ethoxide or chloropropoxide with corresponding alcohol or phenol. The degree (n) of association of these 2-alkoxyethoxides or 2-, 2, 4- and 2, 5-substituted phenoxides was low (n=1.v3). Thesure compounds were very soluble in organic solvents. such as benzene, toluene, and methylene chloride, and were susceptible to hydrolysis, but tin(rr) phenoxides were somewhat more stable to moisture than tin(U) alkoxides.
Further, the method of the direct preparation of tin(ll) compounds from stannous chloride has been examined by using the ring-opening reaction of propylene oxide.
