Ph(3)SnOH或Ph_3SnCl与芳香胂酸RAsO_3 H_2(R= C_6 H_5(1),2-NH_2C_6 H_4(2),4-NH_2C_6 H_4(3),2-NO_2C_6 H_4(4),3-NO_2C_6 H_4(5),4-NO_2C_6 H_4(6),3-NO_2 -4-OHC_6 H_3(7),2-Cl_2C_6 H_4(8),2,4-Cl_2C_6 H_3(9))反应,得到18个Sn-O簇合物。这些化合物可分为四种类型:A型:[{(PhSn)3(RAsO 3)3(μ 3-O)(OH)(R 'O)2}2Sn](R= C6 H5、2-NH 2C 6 H4、4-NH 2C 6 H4、2-NO2 C6 H4、3-NO2 C6 H4、2-ClC 6 H4、2,4-Cl 2C 6 H3和3-NO2-4-OHC 6 H3; R '= Me或Et); B型:[{(PhSn)3(RAsO3)(2)(RAsO3H)(μ 3-O)(R'O)2}2](R=4-NO2C6H4,R'=Me); C型:[{(PhSn)3(RAsO3)3(μ 3-O)(R'O)3}2Sn](R= 2,4-Cl2C6H3,R'=Me); D型:[{Sn3Cl3(μ 3-O)(R'O)3}(2)(RAsO3)4](R=2-NO2C6H4和4-NO2-C6H4; R'=Me或Et)。类型A和B的结构包含[Sn 3(μ 3-O)(μ 2-OR ')2]结构单元,而在类型C和D中,锡氧烷核由两个[Sn 3(μ 3-O)(μ 2-OR')3]结构单元构建。反应在三苯基锡前体部分或完全脱芳基的情况下进行。这些不同的结构形式是通过有机锡前体和芳基胂酸性质的微妙变化实现的。这些有机锡氧烷的合成,结构和结构相互关系进行了讨论。
Reactions of Ph(3)SnOH or Ph3SnCl with aryl arsonic acids RAsO3H2, where R=C6H5 (1), 2-NH2C6H4 (2), 4-NH2C6H4 (3), 2-NO2C6H4 (4), 3-NO2C6H4 (5), 4-NO2C6H4 (6), 3-NO2-4-OHC6H3 (7), 2-ClC6H4 (8) and 2,4-Cl2C6H3 (9), gave 18 Sn-O cluster compounds. These compounds can be classified into four types: type A: [{(PhSn)3(RAsO3)3(mu3-O)(OH)(R'O)2}2Sn] (R=C6H5, 2-NH2C6H4, 4-NH2C6H4, 2-NO2C6H4, 3-NO2C6H4, 2-ClC6H4, 2,4-Cl2C6H3, and 3-NO2-4-OHC6H3; R'=Me or Et); type B: [{(PhSn)3(RAsO3)(2)(RAsO3H)(mu3-O)(R'O)2}2] (R=4-NO2C6H4, R'=Me); type C: [{(PhSn)3(RAsO3)3(mu3-O)(R'O)3}2Sn] (R=2,4-Cl2C6H3, R'=Me); type D: [{Sn3Cl3(mu3-O)(R'O)3}(2)(RAsO3)4] (R=2-NO2C6H4 and 4-NO2-C6H4; R'=Me or Et). Structures of types A and B contain [Sn3(mu3-O)(mu2-OR')2] building blocks, while in types C and D the stannoxane cores are built from two [Sn3(mu3-O)(mu2-OR')3] building blocks. The reactions proceeded with partial or complete dearylation of the triphenyltin precursor. These various structural forms are realized by subtle changes in the nature of the organotin precursors and aryl arsonic acids. The syntheses, structures, and structural interrelationship of these organostannoxanes are discussed.
