yield from the reaction of 2,2′-dilithiodiphenyl ether (I) with dialkyltin dichlorides and, in higher yield, from the reaction of 10,10-dichlorophenoxastannin (III) with organolithium reagents or Grignard reagents. 10,10-Diphenylphenoxastannin could only be obtained by the organolithium and Grignard route. (III) was prepared in high yield by allowing 10,10′-spirobiphenoxastannin (II) to react with
由2,2'-二硫代二苯醚(I)与二烷基锡二氯化物的反应以低收率获得10,10-二烷基苯并氧杂环丁烷酮(环中含CSnC键和环中氧的杂环的第一个实例) 10,10-dichlorophenoxastannin(III)与有机锂试剂或Grignard试剂反应可得到更高的收率。10,10-二苯基苯并氧杂草嘌呤只能通过有机锂和格利雅(Grignard)途径获得。通过使10,10'-螺双苯并氧还丹宁(II)与氯化锡反应以高收率制备(III)。的反应(I)与氯化锡得到三种产品:(II),四(Ô-苯氧基苯基)锡,以及在环(VIII)中包含两个锡原子的新型十二元环杂环。(VIII)与氯化锡的反应产生高产率的(III)。通过使2,2′-二硫代二苯砜与二有机锡二氯化物和氯化锡反应,可获得在环中含有CSnC键和硫的杂环的第一个例子。报告了新杂环的红外,远红外,紫外和NMR数据。
