Our experiments show that primary and secondary alcohols can be smoothly converted into the corresponding MOM-ethers in excellent yields. The methoxymethyl ethers (MOM-ethers) were obtained with good to excellent yields. 1,3-Dichloro-5,5-dimethyl hydantoin [DCDMH] and Poly N,N′-dibromo-N-ethyl naphthyl-2,7-disulfonamide [PBNS] effectively catalyzed the methoxymethylation of alcohols with dimethoxymethane at ambient temperature. The notable advantages of this method are mild reaction conditions, high yields, cheapness, safety and eco-friendliness, and recyclability of the catalysts. %U https://icc.journals.pnu.ac.ir/article_3024_d86e1acd9727bc7dcd9ab5e6bff99b1c.pdf
