Based on the well development of diazo compound transformations in organic synthesis, it is expected to extend its applications field polymer synthesis.It vital importance transform efficient reactions compounds into new polymerization methodology order afford polymers with structures and functions.Currently, there still great potential application synthesis.This review highlights recent advancements synthesis chemistry compounds, including chain-growth polymerization, step-growth end-group functionalization post-polymerization modification.Transition-metal-catalyzed diazoacetates constructs C-C main chain from one carbon unit.Through catalytic diazoacetate high molecular weight polymers, stereocontrol living/controlled can be realized successively.The stepwise originated their conversions.The insertion reaction O-H N-H bonds extended polyethers, polyesters polyamines that are not easily accessible through other synthetic methods, while cross-coupling via metal carbene insertion-migration mechanism realize novel structures.Diazoacetates diazomalonates employed regulate terminal synthesized metal-catalyzed vinyl addition or ring-opening metathesis olefins, successively end-capped by carbene.The modifications based applied introduction polar functional groups polyolefin.Compared copolymerization strategy avoids depressed reactivity varied monomers, applicable a broad scope groups.The thermal mechanical properties improved this method.Finally, future challenges expanding approaches prospected review.
