Methods: An efficient route was started from the cheaper materials alanine and glutamic acid via protection, deprotection and coupling reactions.
Post-azo-coupling reaction was successfully applied to synthesize a series of photorefractive polyphosphazenes P6-P10 containing carbazole-based multifunctional chromophores.
Synthesis of alkynyl 2(5H)-furanone derivatives via Sonogashira coupling reaction
This purified reaction product is used in a second stage: a coupling reaction of the purified activation reaction product with aspartate.
The coupling reaction produced 2 sulfradicals in a molecular chain of PAN with the length two times than that provided by other termination methods.
The results show that unbalance force of atmospheric motion and the coupling reaction among convective cloud cluster and moisture frontal zone and low level jet lead to the continuation of strong convergence in low layer and the maintenance of torrential rain.
Carbon monoxide and nitrous acid ester are synthesized through coupling reaction into diester carbonate in the presence of catalyst and at relatively low pressure and temperature.
