Unusual chemistry in the biosynthesis of the antibiotic chondrochlorens ... B from the myxobacterium Chondromyces crocatus Cm c5 incorporate several unusual structural features, notable among them a shared chloro-hydroxy-styryl functionality and the ethoxy group of chondrochloren B....
6-(4-bromophenyl)-2-ethoxy-4-(4-ethoxyphenyl)nicotinonitrile... The ethoxy group of the 4-ethoxyphenyl is slightly twisted from the attached benzene ring [C—O—C—C = 174.2 (3)°],...
1-[4-(4-chlorobutoxy)-2-hydroxyphenyl]ethanoneIn the title compound, C12H15ClO3, the ethoxy group is nearly coplanar with the benzene ring, making a dihedral angle of 9.03 (4)°,...
Insights into the silanization processes of silicawith and without acid–base additives via tg-ftir and kineticsimulation... Theresults showed that two parallel reactions were included in the silanizationprocess of silica: one is the hydrolysis of the ethoxy group of TESPTfollowed by the condensation with the silanol of silica (the activityenergy is E = 57 kJ/mol), and the other is the directcondensation between the silanol...
