TEMPLATE CONDENSATION IN SYSTEMS SUCH AS "HYDRAZIDES - SnCl <sub>4</sub> - ALDEHYDES - CH <sub>3</sub>CN"
The products of interaction in the systems «hydrazides of 2-R-benzoic, 3-R-2-naphthoic acids (R = H, OH) - SnCl <sub>4</sub> - R’- benzoic aldehydes (R’ = H, 4-N(CH <sub>3</sub>) <sub>2</sub>) - CH <sub>3</sub>CN» were studied and was found, that in the case of (R, R’ = H) were isolated hydrazones (HL), while all the others - complexes, non-electrolytes with them [SnCl <sub>4</sub>(HL)]·n CH <sub>3</sub>CN (n= 1 (I), 2 (II); R = ОН, R’= H) and [SnCl <sub>4</sub>(L∙H)]·n CH <sub>3</sub>CN (n = 0, 1; R = H, ОН,R’= 4-N(CH <sub>3</sub>) <sub>2</sub> (III-VI). In the complexes is realized bidentate O <sub>(C=O/C-O)</sub>, N <sub>(CH=N)</sub> - coordination of ketone (R’ = H) or the enol, the protonated tertiary nitrogen atom of the aldehyde fragment (R’ = 4-N(CH <sub>3</sub>) <sub>2</sub>) form of the ligand. Degradation of I-VI begins dehydrochlorination, but in case I, II removal of chlorine proceeds in one stage in the range of 230-310 °С and in the case of III-VI - in two stages at higher temperatures (280-310 and 320-405 °С). The behavior of I - VI under electron impact was investigated.
