Gilman's reagent mechanism
WebDec 26, 2024 · Abstract A detailed analysis has been made, by use of gas chromatography, of the products of the reaction between a Grignard reagent and an acid chloride, in presence of ferric chloride. Under the most favorable conditions, there may be obtained yields of about 75% for a simple ketone and of about 50% for a 8-keto ester. WebApr 5, 2024 · Bus, drive • 46h 40m.
