Abstract
The present invention provides a compound which can be purified by conventional acid/base extraction. There is disclosed 2-pyridylsilane of formula (1): wherein R1 represents an alkyl group, etc, R2 and R3 represent an alkyl group, an alkoxy group, etc., R4, R5, R6 and R7 represent a hydrogen atom, a halogen atom, an alkyl group, etc.
Claims2
A 2-pyridylsilane of formula (1):
- wherein R1 represents an alkyl group, an aralkyl group, an alkenyl group, an alkynyl group or a silyl group substituted with three groups selected from an alkyl group, an alkoxy group, an aryl group, an aryloxy group and a 2-pyridyl group,
- R2 and R3 are the same or different and independently represent an alkyl group, an alkoxy group, an aryl group, an aryloxy group, and aralkyl group, and aralkyloxy group, an alkenyl group, an alkynyl group or a silyl group substituted with three groups selected from an alkyl group, an alkoxy group, an aryl group, an aryloxy group and a 2-pyridyl group,
- R4, R5, R6 and R7 are the same or different and independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an aralkyloxy group, an alkenyl group, an alkynyl group, a cyano group, a nitro group, a hydroxy group, an alkylsulfonyl group, an arylsulfonyl group or a silyl group substituted with three groups selected from an alkyl group, an alkoxy group, an aryl group, an aryloxy group and a 2-pyridyl group, and
- the alkyl groups, alkoxy groups, aryl groups, aryloxy groups, aralkyl groups, aralkyloxy groups, alkenyl groups and alkynyl groups for R1 to R7 may have a substituent,
- provided that R1 is not a vinyl group, and the aralkyl groups in R1 to R3 may be substituted with at least one group selected from an alkyl, alkoxy, alkoxycarbonyl, aralkyloxycarbonyl, aryloxycarbonyl, cyano, nitro, hydroxy group, and a halogen atom.

A process for producing a 2-pyridylsilane derivative of formula (5):
- wherein X1, X2, X3, X4, X5 and X6 have the same meanings as defined below and X7 represents an ethyl or vinyl group which may have a substituent as its 2-position, which comprises:
- reacting a 1-alkene or a 1-alkyne, in the presence of a transition metal complex catalyst comprising a transition metal of Group 8, 9, or 10 selected from the group consisting of ruthenium, rhodium, iridium, palladium and platinum, and a ligand selected from the group consisting of a halogen atom, a phosphine ligand and an olefin ligand, with a 2-pyridylsilane compound of formula (6):
- wherein X1 and X2 are the same or different and independently represent an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an aralkyloxy group or a silyl group substituted with three groups selected from an alkyl group, an alkoxy group, an aryl group, an aryloxy group and a 2-pyridyl group, and
- X3, X4, X5 and X6 are the same or different and independently represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an aralkyloxy group, a cyano group, a nitro group, a hydroxy group, an alkylsulfonyl group, an arylsulfonyl group or a silyl group substituted with three groups selected from an alkyl group, an alkoxy group, an aryl group, an aryloxy group and a 2-pyridyl group,
- provided that the alkyl groups, alkoxy groups, aryl groups, aryloxy groups, aralkyl groups and aralkyloxy groups for X1 to X6 may have a substituent.
