Benzophenone → HCID 11020538, compound

Participants

Reaction Steps

To 29 g of benzophenone in 150 mL of tetrahydrofuran (THF) at 0° C. was added 88 mL of 2M allyl magnesium chloride. After 16 hrs, the starting material was completely consumed as indicated by thin layer chromatography (TLC). To the reaction mixture was added 1 mL of methanol to quench the excess Grinard reagent. The THF was distilled in vacuo and the residue was shaken with dilute aqueous hydrochloric acid and chloroform. The layers were separated and the aqueous phase was extracted with chloroform. The combined organic layers were dried with sodium sulfate and concentrated in vacuo to give 37 g of 1,1-diphenyl-3-buten-1-ol which is characterized by:
