Abstract
In the present invention, an adamantyl acrylate compound is produced by a process comprising a first step and a second step without using acid halide. In the first step, a 2-adamantanone compound is reacted with a hydrocarbyl halide in the presence of lithium metal to form an adamantanolate intermediate that is then reacted with an acrylic ester compound in the second step to produce the aimed adamantyl acrylate compound.
Claims7
A method for producing an adamantyl acrylate compound represented by the following formula (4):
- wherein Y is hydrogen atom or alkyl group;
- R1 is hydrocarbyl group;
- each of R2 to R4 is independently hydrogen atom, alkyl group, halogen atom or haloalkyl group;
- and n is an integer of 1 to 14,
- the method comprising a first step of reacting a 2-adamantanone compound represented by the following formula (1):
- wherein Y and n are the same as defined above,
- with an alkyl halide represented by the following formula (2):
- R1X (2)
- wherein R1 is the same as defined above and X is halogen atom, in the presence of lithium metal;
- and a second step of further continuing the reaction after adding an acrylic ester compound into a reaction system, the acrylic ester compound being represented by the following formula (3):
- wherein R2 to R4 are the same as defined above and R5 is alkyl group.
