Alternating cationic copolymerization of 2-chloroethyl vinyl ether and cyclic trimers one monomer two aldehyde molecules were investigated to obtain polymers with ABCC-type sequences.

in multi-step organic syntheses, the protection and deprotection of tetrahydropyranyl (thp) ethers is one of the most frequently used methods. over the years, different methods have been used from various catalytic systems for the protection of hydroxyl groups as thp ethers and their deprotection. herein we have reported that various alcohols and phenols have been efficiently converted to the c...
