Reaction of organic tin(II) compounds, Sn(OR)2[R=C2H5, CH2CH2N(CH3)2, C6H5, o-CH3C6H4], with phenyl isothiocyanate and carbon disulfide have been investigated. The reaction of di(ethoxo)tin(II) with phenyl isothiocyanate in benzene at room temperature gave the corresponding addition product. The reaction at 80–81 °C however gave diethyl N-phenylcarbonimidate. Phenyl isothiocyanate reacted exothermically with bis[2-(dimethylamino)ethoxo]tin(II) to yield the 1 : 1 addition product. In the reaction with bis(2-methylphenoxo)tin(II), a compound containing one molecule of phenyl isothiocyanate per two molecules of the tin(II) compound was isolated, but the reaction with di(phenoxo)tin(II) did not occur. Di(ethoxo)tin(II) reacted with carbon disulfide to give diethyl thiocarbonate, diethyl carbonate, and tetraethyl orthocarbonate. Bis(o-methylphenoxo)tin(II) and di(phenoxo)tin(II) however did not react with carbon disulfide.
