A facile conversion of substituted cyclobutanones to cyclopentanones by CH2I2/SmI2 system
Fukuzawa, Shin-Ichi,Tsuchimoto, Teruhisa
, p. 5937 - 5938 (1995)
Ring expansion reaction of a substituted cyclobutanone with CH2I2 and SmI2 proceeded cleanly in extended reaction time (15 h) to afford the corresponding cyclopentanone in good yield, whereas short reaction time (0.5 h) pr
