Bis(triorganostannyl) esters of phenylmaleic acid, citraconic acid, maleic acid, phenylsuccinic acid, methylsuccinic acid and succinic acid, R3SnO2CCR1: CHCO2SnR3 (R Bu, Ph, Cy; R1 Ph, Me, H) and R3SnO2CCHR1·CH2CO2SnR3 (R Bu, Ph; R1 Ph and R Bu, Ph, Cy; R1 Me, H), have been prepared from R3SnOH or (BU3Sn)2O and the dicarboxylic acid or its anhydride. The structures of these compounds in the
双(triorganostannyl)苯基马来酸,柠康酸,马来酸,苯基琥珀酸,甲基琥珀酸和琥珀酸,R的酯3的SnO 2 CCR 1:CHCO 2 SNR 3(R卜中,Ph中,Cy; R 1 PH,我,H)和R 3的SnO 2 CCHR 1 ·CH 2 CO 2 SNR 3(R卜中,Ph; R 1 博士和R卜中,Ph中,Cy; R 1 箱,H)已被选自R制备3 SnOH或(BU 3 Sn)2O和二羧酸或其酸酐。参照其IR和Mössbauer光谱讨论了这些固态化合物的结构。苯基马来酸和柠康酸的双(三苯基锡烷基)酯的晶体结构已经通过单晶X射线衍射测定。在第一个二酯中,两个锡原子都占据四面体的几何形状,没有短的分子间O⋯Sn接触。在柠檬酸双(三苯基锡)酯中,与取代的烯烃碳原子相连的羧甲基锡素也具有四个配位基,但是第二个锡原子也具有五个配位基,这是由于相邻分子的羧酸酯基之间的分子间配位[Sn
