4-dimethylpyridine（DMAP） was used as catalyst for preparing benzimidazolyl phenoxyacetic acid O-acetyllactopyranosyl saccharide carboxylate and triethylamine（Et3N） was used as deacid reagent.Three saccharide carboxylates were synthesized from saccharide carboxylation at room temperature in the system of DMAP/Et3N with nitro-containing,trifluoromethyl benzimidazolyl phenoxyacetic acid with as lead compounds.The catalytic mechanism of DMAP/Et3N was discussed.The results showed that DMAP is a effective catalyst.The yields can reach over 52.7%.The test indicated that the compounds showed better antiviral activity against tobacco mosaie virus（TMV）.
3-Chloro-2-（chloromethyl）-1-propene（CCMP） was synthesized and used to initiate atom transfer radical polymerization（ATRP） of styrene catalyzed by copper（Ⅰ） chloride/2,2′-bipyridine at 125℃.As a difunctional initiator,CCMP can initiate ATRP of styrene with two living end sites at the same time.The structure of the obtained α,ω-chloropolystyrene was confirmed by（）1H-NMR spectra.The living character of the ATRP process is indicated by narrow molecular weight distributions of the obtained polystyrene（Mw/Mn<1.5）,a linear（ln（[M]0/[M]）） versus time profile and predictable molecular weights proportional to monomer conversion.
