    Abstract: PROBLEM TO BE SOLVED: To obtain a new compound useful as a raw material for a new compound utilizing a naphthalene skeleton, a raw material for a monomer for a polyether, a polysulfide and a polythioester, and the like. SOLUTION: This new compound is represented by formula I (X is oxygen or sulfur; R is an alkyl, an aryl, an aralkyl or the like; Z is H, a halogen, an alkyl or the like), and exemplified by 6,7-bis[(methoxy)methyl]-2-oxa-2,3- dihydrophenalene. The compound of formula I is obtained by reacting a compound of formula II (Y is a halogen), [e.g. 1,4,5,8-tetrakis(bromomethyl) naphthalene] with a metal alkoxide such as sodium methoxide, or a metal thioalkoxide such as sodium methylthiomercaptide in an organic solvent such as methanol, preferably at a temperature from room temperature to about 100 deg.C, usually for 10-30 hr.
