摘要：

The reactions of (LLi)-Li-1 [L-1= HC(CMeNAr)(2), Ar= 2,6'-iPr(2)C(6)H(3)] with Me2SnCl2, and (LLi)-Li-2 [L-2= HC(CMeNAr')(2), Ar'= 2,6-Et2C6H3] with Me3SnCl in a molar ratio of 1: 1 were carried out at room temperature and acquired two new compounds, N(Ar)= C(Me)CH= C(NHAr)CH2SnMe2Cl center dot C7H8 (1) and [N(Ar')C(Me)=CHC(=NAr')CH2SnMe2](2)center dot CH2Cl2(2), respectively. Different from regular nitrogen-metal-nitrogen bonds generated by the reactions of beta-diketiminato ligands with metal halides, uncommon nitrogen-tin-carbon bonds in compounds 1 and 2 were obtained by Sn-N bond cleavage and concomitant Sn-C bond formation due to the Lewis acidity of SnMe3 and SnMe2Cl group. Compound 2 is a rare tin dimer with two resonant structures. Two compounds have been confirmed by H-1 NMR, C-13 NMR, elemental analysis, and single crystal X-ray structural analysis. Through the comparison of compounds 1 and 2, the formation mechanism of dimer 2 has been investigated.
