Abstract:
A process for producing one or a mixture of pyridine compounds represented by general formula (3): whereinR1, R2, and R3, independently, represent substituted or non-substituted alkyl group, alkenyl group, aromatic group, silyl group, alkoxy group or ester group of carbon number 1 to 20; and, R4 and R5, independently, represent a substituted or non-substituted allyl group, alkenyl group, aromatic group, silyl group, alkoxy group, or ester group of carbon number 1 to 20, which comprises reacting azametallacyclopentadiene represented by general formula (1) â€ƒwherein R1, R2, and R3, are as defined above, M represents an early transition metal; L represents a group selected from the group consisting of cyclopentadienyl group, indenyl group, fluorenyl group, azurenyl group, hydrocarbonoxy group, amide group, acetylacetonate group, carboxyl group, phosphine ligand, amine ligand and ether ligand; M and L may be bonded directly or via a bridging group; and, n represents an integer of 1 to 4; and, when n is 2, 3 or 4, the groups L may be the same or different; with at least one alkyne represented by general formula (2) â€ƒwherein R4 and R5 are as defined above, in organic solvent, in the presence of transition metal complex.
