A naphthalene derivative, binaphthalene derivative and biphenyl derivative, all having an oxetane group, capable of being cationically polymerized and a cationically curable compound containing a naphthalene derivative having an oxetanyl group and an aromatic compound having an epoxy group or an oxetanyl group.

Cationically curable oxetanyl-containing naphthalene and aromatic epoxy or oxetane compound

Naphthalene derivative, binaphthalene derivative and biphenyl derivative and cationically curable compound

The present invention is to provide for a process for producing 3-chloromethyl-3-alkyloxetanes from a 1,1-bis(chloromethyl)-1-hydroxymethylalkane or its carboxylate ester through a dehydrogen chloride reaction or a deacid chloride reaction in an aqueous solution or suspension of an alkaline compound. The reaction is conducted, either in the presence of a phase transfer catalyst or an anion exchange resin having an ammonium group, or, while distilling the formed 3-chloromethyl-3-alkyloxetane out azeotropically with water. The invention enables one to produce 3-chloromethyl-3-alkyloxetanes within a shorter period of time and with a higher yield, and thus the process is much advantageous and useful from the industrial points of view.
