A modified Merrifield polymer containing acid chloride groups was used in the selective synthesis of the monotrityl ethers of the symmetrical diols, HO—(CH 2 ) n —OH, where n = 2, 4, 6, 8, and 10. This procedure constitutes a unique method of blocking one functional group of a completely symmetrical difunctional compound.
