Chemistry of 2-Methoxy-2,5-cyclohexadienones. III. Syntheses of 2-Methoxy-4,4-diphenyl-2,5-cyclohexadienone and 4-Dichloromethyl-2-methoxy-4-methyl-2,5-cyclohexadienone
2-Methoxy-4,4-diphenyl-2,5-cyclohexadienone (Ib) was synthesized by phenylselenylation of 2-methoxy-4,4-diphenyl-2-cyclohexenone (Va) followed by oxidative deselenylation of the resultant 6-phenylselenyl derivative (Vc). 4-Dichloromethyl-2-methoxy-4-methy
