Abstract
A method for producing an allyl compound having a compositional formula different from that of an allyl starting material compound, which comprises reacting the allyl starting material compound with an oxygen nucleophilic agent in the presence of a catalyst containing at least one transition metal compound containing a transition metal selected from the group consisting of transition metals belonging to Group 8 to Group 10 of the Periodic Table and a multidentate phosphite compound.
Claims18
A method for producing an allyl compound comprising:
- reacting a first allyl compound of formula (a) with an oxygen nucleophilic agent in the presence of a catalyst containing a multidentate phosphite compound and at least one transition metal compound containing a transition metal selected from the group consisting of transition metals belonging to Group 8 to Group 10 of the Periodic Table, under conditions suitable for producing a second allyl compound,
- wherein the second allyl compound has a compositional structure different than that of the first allyl compound, and
- wherein formula (a) is:
- wherein Ra to Re are independently a hydrogen atom, a halogen atom, a hydroxyl group, an amino group, a formyl group, an alkyl group, an aryl group (including a heterocyclic compound forming an aromatic 6π electron cloud on the upper and lower sides of the ring, hereinafter the same), an acyloxy group, an aryloxy group, an alkylthio group, an arylthio group, an amide group, an acyl group or an acyloxy group;
- among these groups, the amino group, the alkyl group, the aryl group, the alkoxy group, the aryloxy group, the alkylthio group, the arylthio group, the acyl group or the acyloxy group may have a substituent;
- and
- when any of Ra to Re has a carbon chain, the carbon chain may have at least one carbon-carbon double bond or triple bond;
- X is a halogen atom, a hydroxyl group, a nitro group, an amino group, a sulfonyl group, a sulfonate group, an acyloxy group, a carbonate group, a carbamate group, a phosphate group, an atkoxy group or an aryloxy group;
- among these groups, the amino group, the sulfonyl group, the, sulfonate group, the acyloxy group, the carbonate group, the carbamate group, the phosphate group, the alkoxy group and the aryloxy group may have a substituent;
- when X has a carbon chain, the carbon chain may have at least one carbon-carbon double bond or triple bond;
- and
- at least two optional groups among Ra to Re and X may bond to each other to form at least one cyclic structure;
- wherein the oxygen nucleophilic agent is not the same as the X of the first allyl compound, X−, or the proton adduct of X.
