A new synthetic methodology for pyridinic sucrose esters and their antibacterial effects against Gram-positive and Gram-negative strains
(2020-03-01)
Described are the development of a new synthetic method using ultrasonic irradiation and sodium methoxide as catalyst for a series of pyridinic sucrose esters (py-SEs), derived from transesterification of sucrose with ...
Thermal studies of poly(esters) containing silicon or germanium
(SOCIEDAD CHILENA DE QUIMICA, 2001)
The thermal properties of poly(esters) containing silicon or germanium in the main chain and derived from the diphenols bis(4-hydroxyphenyl)-diphenylsilane and bis(4-hydroxyphenyl)-diphenylgermane and isophthaloyl or ...
A New Look at the Halogenation of Porphyrins
(Bentham Science Publishers, 2016-12)
The present study describes the selective halogenation at the β - or meso-position of the porphyrin macrocycle. The reactions of deuteroporphyrin IX dimethyl ester, mesoporphyrin III dimethyl ester and their Cu(II) and ...
