There is provided a process for preparing a carboxylic acid ester of formula (3):RCOOR&#x2003;&#x2003;(3)wherein Ris

Process for the preparation of carboxylic acid esters

Disclosed is a method for producing a primary amine compound represented by the formula (2) below, which is characterized in that a halogen compound represented by the formula (1) below, ammonia and formaldehyde are reacted with each other, and then the thus-obtained reaction product is [1] brought into contact with an aqueous solution of an acid or [2] reacted with a hydroxylamine under acidic conditions. By this method, a primary amine compound can be commercially advantageously produced by using a low-cost ammonia while suppressing production of a secondary amine as a by-product. (1) (In the formula, Rand Rindependently represent a hydrogen atom, a C1-C5 alkyl group which may be substituted by a halogen atom or the like, a C1-C5 alkoxy group which may be substituted by a halogen atom, a cyano group, a C2-C11 alkenyl group or a phenyl group or the like; Rrepresents a hydrogen atom, a linear or branched C1-C5 alkyl group or a cyano group; and X represents a halogen atom.) (2) (In the formula, R, Rand Rare as defined above.)

A cyclopentadienyl metal salt is prepared by reacting a cyclopentadiene and a metal hydride in the presence of an amine compound. Furthermore, a derivative of a cyclopentadiene in which a phenyl group is bonded to its cyclopentadienyl moiety through an element of the 14 group of the Periodic Table is prepared using such a reaction.
