Bischloroformate

As the dimeric bischloroformate itself undergoes hydrolysis, a key intermediate is formed, an oligomer with one phenoxide and one chloroformate end-group. This species can either form a cyclic oligomer or undergo further intermolecular reaction with incoming bischloroformate to form a trimer-bischloroformate which can undergo cyclization or be ... WebA-bischloroformate (BABC) has recently found increasing interest, because it allows syntheses of cyclic oligocarbo- nates and cyclic polycarbonates in high yields.
