Rh‐catalyzed polymerization of a new N‐propargylamide monomer having a galactose residue was investigated. The polymerization proceeded in a mixed solvent of THF and water to produce the galactose‐carrying poly(N‐propargylamide) consisting of cis‐isomer. The copolymerization of the monomer with the N‐propargylamide having the alkyl chain was also carried out.  相似文献

Methods of synthesis of acylate phosphabetaines by reactions of triphenylphosphine with methacrylic, cinnamic, and p-methoxycinnamic acids are developed. The phosphabetaine form is proposed to exist in equilibrium with the 5-oxaphospholane form. The features of methylation of the phosphabetaines are discussed.  相似文献
