N, N-dimethylpropenylurea (DMPU) rau kev npaj thiab qauv ntawm alkaline ntiaj teb hlau iodide phosphine oxide thiab urea complexes.

Non-polar hnyav, tsis tshua muaj toxicity, lub teeb thiab kub tsis kam, muaj zog acid thiab alkali tsis kam, solubility zoo, muaj peev xwm yaj ntau yam organic, inorganic, macromolecules, thiab lwm yam. thiab ncua sij hawm ua haujlwm.

DMPU yog ib tug multifunctional aprotic polar hnyav rau N-alkylation ntawm chiral thawj amines, O-alkylation ntawm aldoses thiab synthesis ntawm poly (aryl ethers); nws tuaj yeem hloov kho Chemicalbook's carcinogenic HMPA, ua raws li cov kuab tshuaj rau cov nucleophiles thiab cov hauv paus; muaj siab Z-selectivity nyob rau hauv enolate tsim; DMPU qhia tias tsis muaj kev hloov pauv thiab kev nyab xeeb.
