Process for Production of Alkyl Tin Alkoxide Compound, and Process for Production of Carbonic Acid Ester Using the Compound

The present invention provides a process for producing: a compound represented by XOR2; a dialkyl tin dialkoxide compound having one tin atom, two Sn—R1 bonds and two Sn—OR2 bonds; and/or a tetraalkyl dialkoxy distannoxane compound having one Sn—O—Sn bond, in which each tin atom of the tetraalkyl dialkoxy distannoxane compound has two Sn—R1 bonds and one Sn—OR2 bond, the process comprising reacting in the absence of a catalyst at least one alkyl tin compound selected from the group consisting of i) and ii) below: i) a dialkyl tin compound having one tin atom, two Sn—R1 (wherein R1 represents an alkyl group) bonds, and two Sn—OX bonds (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); andii) a tetraalkyl distannoxane compound having one Sn—O—Sn bond, in which each tin atom of the tetraalkyl distannoxane compound has two Sn—R1 bonds and one Sn—OX bond (wherein OX is a group in which HOX that is a conjugate acid of OX is a Bronsted acid having a pKa of from 0 to 6.8); anda carbonic acid ester represented by R2OCOOR2 (wherein R2 represents a linear or branched, saturated or unsaturated hydrocarbon group, a hydrocarbon group having a saturated or unsaturated cyclic hydrocarbon substituent, or a Y—CH2— group (wherein Y represents an alkyl polyalkylene group, an aromatic group or a cyclic saturated or unsaturated alkylene ether group)), and/oran alcohol represented by R2OH (wherein R2 is the same as defined above).
