A facile reaction of aryl Grignard reagents with 4-alkylacetophenones under ultrasonic irradiation is reported. The reaction can be completed within two minutes with a conversion of 15%~95% and gives 1,1-diarylethene and tertiary alcohol in the selectivity over 60%~96%(sometimes with 94.4% 1,1-diarylethene).
- alkylacetophenone,
- aryl Grignard reagent,
