An efficient synthesis of functionalized benzofurans is achieved under mild and metal-free conditions from stable para-quinone methides by treatment with phosphine, acyl chloride, and a base. This one-pot phospha-1,6-addition/O-acylation/Wittig reaction i

In aqueous ethanol 1-aryl-5,7-di-t-butyl-2-(o-methoxyphenyl)-spiroocta-1,4,7-trien-6-one 4 changed to 2-aryl-3-(3',5'-di-t-butyl-4'-hydroxyphenyl)benzofuran 5 in a more than 90percent yield.The selective formation of 5 is ascribed to a neighbouring group participation of the ortho-methoxyl group to an incipient vinyl cation.
