of R(2)SnCl(2) (R = Me, (i)Pr, (n)Bu) to solutions of 1, 3, and 4, respectively, causes displacement of (t)Bu(2)SnCl(2) with concomitant formation of [((t)Bu(2)SnCl(2))(R(2)SnO)(2)(R(2)SnCl(2))] and [(R(2)SnCl(2))(R(2)SnO)(2)(R(2)SnCl(2))]. Thus 1-4 can be regarded as (R(2)SnO)(2) units which are stabilized by two (t)Bu(2)SnCl(2) molecules. NMR data indicate that reaction between ((t)Bu(2)SnO)(3) and
二叔丁基氧化锡((t)Bu(2)SnO)(3)与R(2)SnCl(2)反应生成混合的二锡烷[[t)Bu(2)(Cl)SnOSn(Cl) R(2)](2)(1,R = Me; 2,R = Et; 3,R =(i)Pr; 4,(n)Bu),而二叔丁基氢氧化锡氯化物,[[t) Bu(2)Sn(OH)Cl](2),与[(n)Bu(2)SnO](n)反应,得到氯羟基二恶烷[[t)Bu(2)(OH)SnOSn(Cl)(n) )Bu(2)](2),5; 通过测定晶体结构1和4证实了这些四有机二锡氧烷的二聚性质。尽管在固态下稳定,但化合物1-4重排后在溶液中产生了许多二锡氧烷。将R(2)SnCl(2)(R = Me,(i)Pr,(n)Bu)加到1、3和4的溶液中会导致(t)Bu(2)SnCl(2)的位移)伴随形成[[((t)Bu(2)SnCl(2))(R(2)SnO)(2)(R(2)SnCl(2))]和[(R(2)SnCl(2
