Dichloromethane naoh reaction
WebSep 18, 2003 · A mixture of 5 % NaOH-MeOH (0.6 mL) and 30 % H 2 O 2 (6 mL) was added to a solution of the trienone 2 (3 g, 7.34 mmol) in methanol (60 mL). The mixture was stirred at room temperature for 22 hours, at which time TLC indicated reaction completion, then extracted with dichloromethane. WebMost dichloromethane does contain a small amount of alchohol (typically methanol) as a preservative to prevent formation of HCl; perhaps this would allow you to dissolve some of the NaOH. I would ...
