o:6924 Proučavanje reaktivnosti karboksilnih kiselina metodom linearne korelacije solvatacionih energija The study of the reactivity of carboxylic acids by the method of linear solvation energy correlations sr U cilju proučavanja uticaja rastvarača na reaktivnost organskih molekula odabrana je kao model reakcija karbo ksi lnih kiselina sa diazodifenilmetanom (DDM). Odredjene su konstante brzina za karbo ksilne kiseline sa cikličnim ugljovodničnim nizom, različite strukture, sa različitim brojem ugljenikovih atoma u prstenu, u nizu protičnih i aprotičnih rastvarača. Diskutov an je uticaj strukture molekula kiseline i svojstava rastvarača na kinetiku i mehanizam reakcije karbo ksilnih kiselina i diazodifenilmetana... As a part of the research of solvent influence on the reactivity of organic compounds the reaction of carboxylic acids with diazodiphenylmethane(DDM) was chosen as a model. Rate constants for acids of various structure: cycloalken e carboxylic and cycloalken e acetic with a differen t number of carbon atoms in the ring, were determined in a wide range of protic and aprotic solvents. The influe nce of the moleculars structure and solvent properties on the kinetics and mechanism of the reaction of carboxylic acids with DDM was discussed...
