Answer to: What's the product when 1,3 butanediol react with a) PCC/CH2Cl2 b)Na2CrO7/H2SO4, H2O and 1-methyl 1,2-cyclohexanediol react with...
The epoxide (176) reacts with 2-aminopyrimidine in acetonitrile containing HBr to yield an initial enaminoimidazole. The two carbons of the epoxide then act as electrophilic centers allowing cyclization to (177) in 54% yield 〈86T1169〉. Condensation of epoxide (178) with 2-aminopyrimidine ga...
Most [4+2] cycloaddition reactions with anthracene(s) as the 1,3‐diene component require significant thermal activation (see below for some examples).[21] Therefore, we were delighted to find that 3‐CF3‐propeniminium salts 5 b,d–f reacted with anthracene and some substituted anthracene...
Au/TiO_2 catalysts form hydroperoxy species from H_2O-O_2 mixtures at near-ambient temperatures; these species can be used in the selective epoxidation of propene to propylene oxide.rnPropylene oxide (PO) is a useful intermediate in the synthesis of polyurethane, organic intermediates and ...
