Abstract

Reactions of dibutyltin dichloride with potassium amides KNH-pap, KNH-4pbt, and KNH-2pbt (pap = 4-(phenylazo)phenyl; 4pbt = 1,3-benzothiazol-2-yl-4-phenyl; 2pbt = 1,3-benzothiazol-2-yl-2-phenyl) were studied. It was found that KNH-pap and KNH-4pbt yield only the stannandiamines nBu2Sn(NH-pap)2 (I) and nBu2Sn(NH-4pbt)2 (II), respectively. However, the reaction with KNH-2pbt gives an inseparable mixture of the stannandiamine nBu2Sn(NH-2pbt)2 (III) and the cyclodistannadiazane [nBu2Sn(N-2pbt)]2 (IV). The molecular structures of compounds I–IV were determined by single-crystal X-ray diffraction of phases I·0.5C7H8, II·0.5THF, III, and IV (CCDC nos. 2367378 (I·0.5C7H8), 2367379 (II·0.5THF), 2367380 (III), and 2367378 (IV)).
