(β-Carboalkoxyethyl)tin trihalides and bis(β-carboalkoxyethyl)tin dihalides react with metallic zinc to give mixtures of the corresponding tris(β-carboalkoxyethyl)tin halides and the tetra(β-carboalkoxyethyl)tins.Bis(β-carboalkoxyethyl)tin diacetates react with metallic zinc to give only the corresponding tetra(β-carboalkoxyethyl)tin compounds.The mechanisms of these reactions are discussed.Conversion of the bis(β-carboalkoxyethyl)tin dihalides into the tris(β-carboalkoxyethyl)tin halides is believed to occur by a two-step process, with the tetra(β-carboalkoxyethyl)tin compounds as intermediate products.The 270 MHz NMR spectra of the (β-carbobutoxyethyl)tin compounds are presented.
Process for the preparation of organotin compounds
-
, (2008/06/13)
Organotin compounds having the formula R3 SnX or R4 Sn are prepared by reacting metallic zinc with organotin compounds having the formula RSnX3 or R2 SnX2, wherein X stands for chlorine, bromine, iodine or an alkyl carboxylate group having the formula Cp H2p+l COO, wherein p=1-18, and R represents an organic group. Satisfactory yields are obtained under mild reaction conditions and without any catalyst being needed if both in the reacting organotin compounds and in the organotin compounds obtained the group R has the structure STR1 with A being selected from the group consisting of alkyl having 1-18 carbon atoms, O-alkyl having 1-18 carbon atoms and optionally carrying an alkoxy group having 1-18 carbon atoms, polyoxyalkylene consisting of oxyalkylene groups having 1-4 carbon atoms and carrying as terminal group alkyl or a hydrogen atom, O-cycloalkyl, O-alkenyl having 2-4 carbon atoms, O-phenyl, NH2 and alkyl substituted amino, and Cl.
