Abstract
(2) This cleavage reaction was particularly prone to occur during removal of excess reagent and ethanol solvent on the rotary evaporator (40-50" C) during workup of the reaction.(3) Most of the reactions were carried out overnight for convenience (15-24 h). When the progress of the reaction was monitored by TLC, the reactions were usually completed in 5 h or less.
