The reactions of SnPh3[(CH2)nSC6H4Me-p](n= 3 or 4) with mercury(II) chloride, bromine, and iodine lead to phenyl–tin bond cleavage. In contrast, reactions with methyl iodide provide SnPh3[(CH2)nI] and MeSC6H4Me-p. Charge-transfer adducts are formed between SnPh3[(CH2)nSC6H4Me-p](n= 1–4) and tetracyanoethylene or p-bromoanil. The values of λmax. of the complexes indicate similar donor character for
SnPh 3 [(CH 2)n SC 6 H 4 Me- p ](n = 3或4)与氯化汞(II),溴和碘的反应导致苯基锡键断裂。相反,与甲基碘的反应提供了SnPh 3 [(CH 2)n I]和MeSC 6 H 4 Me- p。在SnPh 3 [(CH 2)n SC 6 H 4 Me- p ](n= 1-4)和四氰基乙烯或对溴苯胺。λmax的值。的配合物表明SnPh 3 [(CH 2)n SC 6 H 4 Me- p ](n = 2、3或4)具有相似的供体特征;然而,该化合物SnPh 3(CH 2 SC 6 H ^ 4 ME- p)是较强的供体。
