チオール酸エステルのラネーニッケルによる脱硫還元分解 (第2報)

ジカルボン酸モノチオールエステルについて

抄録

Reductive desulfurization decompositions have been investigated on two series of following compounds:
[A] Monothiol benzyl esters of succinic, phthalic, and telephthalic acids, and salicylic acid thiol benzyl ester.
[B] Ethyl thiol benzyl diesters of succinic, phthalic, and telephthalic acids, and thiol benzyl ester of o-methoxybenzoic acid.
The result indicated that the compounds of [B] series showed far greater yield in reductive product than those of [A] series.The cause of this difference may be explained that thiol ester groups in [A] series with intramolecular or intermolecular hydrogen bonding have difficulty to be adsorbed on the catalyst than those of [B] series having thiol groups without such hydrogen bonding.
