The present invention is a method for producing a cycloalkyl alkyl ether compound comprising reacting substituted or unsubstituted cyclopentene or substituted or unsubstituted cyclohexene with an alcohol compound represented by a formula (2): R
1
OH (wherein R
1
is a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted cycloalkyl group having 3 to 8 carbon atoms) in a gaseous state in presence of an acidic ion-exchange resin to produce a cycloalkyl alkyl ether compound represented by a formula (1): R
1
—O—R
2
(wherein R
1
is the same as defined above, and R
2
is a substituted or unsubstituted cyclopentyl group or a substituted or unsubstituted cyclohexyl group), the acidic ion-exchange resin having a specific surface area of 20 to 50 m
2
/g, an average pore size of 20 to 70 nm, and a total exchange capacity of 4.8 to 6.0 eq/L-R wet resin.

A novel method for the mild and efficient synthesis of allyl sulfides has been developed with allyl alcohols and thiols as substrates. The desired allyl sulfide was obtained using a catalytic amount of Sn(OTf)2 in dichloromethane at room temperature after a reaction time of 12 hours. A diverse range of allyl sulfides have been obtained with good to excellent yields, including both linear and cyclic
