几种新型二烃基锡羧酸酯类化合物的合成与表征

Synthesis and Characterization of Difluorous Tin Carboxylate Compounds

以二氟碳基锡氧化物(n-C6F13CH2CH2)2SnO,二正丁基锡氧化物(n-C4H9)2SnO和不同结构的芳香羧酸ArCOOH为原料,较高产率(68%～95%)地合成了尚未见文献报道的7种二烃基锡羧酸酯类化合物,并对这些化合物进行了表征.这些化合物属于两种构型{[R2Sn(OOCAr)]2O}2(A)和R2Sn(OOCAr)2(B),在这两类化合物(A)和(B)中,中心锡原子具有不同的配位形式和配位数.

Seven organotin carboxylate compounds not yet published in any document were synthesized through the reaction of difluoroalkyltin oxide （ n-C6F13CH2CH2 ）2SnO or dibutyltin oxide （ n-C4Hg）2SnO with ArCOOH with high yields （68 % - 95 % ）, and these compounds were characterized with ^1H NMR. These compounds were classified into two types of structures： {[ R2Sn（OOCAr）]2O}2 （A） and R2Sn（OOCAr）2 （B）. The central stannnic atoms in A and B types possessed different coordinate models and coordinate numbers.
