Offene und cyclische Methylstibonigsäureester. II

Esters of Methylstibonous Acid. II. The reaction of methyldibromstibine with sodium alcoholates and phenolates yield methyldialkoxi and methyldiphenoxistibines. Interchange reactions of the methyldiethoxistibine with thiols, 1,2-diols, 1,2-dithiols, and 2-mercapto-1-oles form dithioesters and cyclic esters of the methylstibonous acid in nearly quantitativ amount and high purity.
