Procedure
1-Indanone (13.30 g, 0.1006 moles) was stirred in diethylether (300 mL) at -78° C. as PhMgBr (0.150 moles, 50.00 mL of 3.0M solution in diethylether) was added. The mixture was then allowed to slowly warm to 20°-25° C. and then stirred 16 hours. After the reaction period the mixture was poured on ice and then extracted with aqueous solutions of 1M HCI (1×100 mL), 1M NaHCO3 (1×100 mL), andthen H2O (1×100 mL). The organic layer was then dried over MgSO4. Filtration followed by removal of the volatiles resulted in the isolation of a yellow oil which by NMR was seen to still contain some 1-phenyl-1-indanol. This oil was then distilled under vacuum to yield the desired product as a pale yellow oil (18.56 g, 95.9 percent).
