Methylenation of 1, 2-dihydroxy-3-, 1, 2-dihydroxy-4-, 1, 2-dihydroxy-3, 4-dimethoxy-5- and 1, 2-dihydroxy-3-methoxy-5-allylbenzenes with methylene dichloride in DMF or DMSO was found to be accelerated more effectively by nickelous oxide than metallic nickel and nickelic oxide, as catalyst. DMF and DMSO gave better results than other solvents.
