Aromatic α-ketols reacted with diethylaminotributylstannane at 60 °C to afford a mixture of (Z)- and (E)-1,2-bis(tributylstannyloxy)-1,2-diarylethenes, which were allowed to react with organic isothiocyanates and carbon disulfide to give substituted O,O-vinylene imino- and thiocarbonates, respectively. Aliphatic α-ketol, 3-hydroxy-2-butanone, was treated by the aminostannane, followed by the reaction with carbon disulfide to form (E)-1,2-bis(tributylstannylthio)-2-butene.
芳香族α-酮醇在60°C下与二乙氨基三丁基锡反应,生成(Z)-和(E)-1,2-双(三丁基锡氧基)-1,2-二芳基乙烯的混合物,这些混合物进一步与有机异硫氰酸酯和二硫化碳反应,分别得到取代的O,O-乙烯基亚胺碳酸酯和硫代碳酸酯。脂肪族α-酮醇,3-羟基-2-丁酮,经氨基锡化合物处理后,再与二硫化碳反应,形成(E)-1,2-双(三丁基锡硫基)-2-丁烯。
