Abstract
The phase transfer catalytic(PTC)synthesis of 4-methoxy-β-methyl-β-nitrostyrene under microwave irradiation was reported in this paper .Through a series of experiment ,the effects of different factors ,such as the power of microwave irradiation(MWI),the time of microwave irradiation , the choice of PTC reagent ,PTC reagent amount and the mol ratio of compounds had been investigated . The optimal conditions were that PEG-1000 was selected as PTC, the PTC usage was 8% of the 4-methoxybenzaldehyde mol amount, the power of irradiation was130W,the reaction time was 8min, the mol ratio of 4-hydroxybenzaldehyde to nitroethane was 1∶2.5∶0.08, the yield were 48.9%.
