Bis-silicon-bridged stilbene derivatives were synthesized in a modified procedure that combined the preparation of bis[2-(silyl)phenyl]acetylene and its intramolecular reductive cyclization in one pot. The results indicated that the one pot approach produced target products in a comparable yield to that of the two-step method reported previously.
Atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) employing ethyl 2-bromoisobutyrate (EBiB)/CuBr as the initiating system was investigated at 50°C in the absence of any additional ligand in the three room temperature ionic liquids (RTILs), 1-methyl-imidazolium acetate ([mim][CH 3 COO]), 1-methylimidazolium propionate ([mim][CH 3 CH 2 COO]) and 1-methylimidazolium...
