| titleOfInvention | Heavy metal catalyst for ring-opening addition reaction of heterocyclic compounds |
| abstract | An object of the present invention is to provide a metal catalyst for a ring-opening addition reaction having very few side reactions such as a transesterification reaction. A metal catalyst for a ring-opening addition reaction of a heterocyclic compound (b) with an active hydrogen compound (a) containing a carbonyl group and / or a thiocarbonyl group, comprising zirconium, hafnium, niobium, tantalum, molybdenum, A heavy metal catalyst comprising a heavy metal element selected from the group consisting of tungsten, ruthenium, and osmium is used. The active hydrogen compound (a) is a carboxylic acid, a carboxylic acid ester, an amide, an imide, a carboxylic acid salt, a thiocarboxylic acid, a thiocarboxylic acid ester, a thiocarboxylic acid amide, a thiocarboxylic acid imide, a thiocarboxylic acid salt, a carboselenic acid, a carboselenothioic acid, or a carboselene. It is preferably a compound selected from the group consisting of acid salts, carboselenothioates and compounds represented by the general formula (1).
