Abstract
The objective of the present invention is to provide a method for producing a carbonate derivative in a safe and efficient manner. The method for producing a carbonate derivative according to the present invention is characterized in comprising irradiating light on a composition containing a C1-4 halogenated hydrocarbon having one or more kinds of halogen atoms selected from the group consisting of a chlorine atom, a bromine atom and an iodine atom, a nucleophilic functional group-containing compound and the specific base in the presence of oxygen.

A method for producing a carbonate derivative, comprising
- irradiating a light on a composition containing a C1-4 halogenated hydrocarbon having one or more halogen atoms selected from the group consisting of a chlorine atom, a bromine atom and an iodine atom, a nucleophilic functional group-containing compound and a base in the presence of oxygen,
- wherein the nucleophilic functional group-containing compound is represented by the following formula (i) and the carbonate derivative is a linear carbonate derivative represented by the following formula (I), or
- the nucleophilic functional group-containing compound is represented by the following formula (ii), Bisphenol A, Bisphenol AP, Bisphenol B, Bisphenol BP, Bisphenol TMC or Bisphenol Z, and the carbonate derivative is a polycarbonate derivative containing a unit represented by the following formula (II-1), a polycarbonate ester of Bisphenol A, Bisphenol AP, Bisphenol B, Bisphenol BP, Bisphenol TMC or Bisphenol Z, or a cyclic carbonate derivative represented by the following formula (II-2):
- wherein
- A is O, S or NR3 wherein R3 is H or a C1-4 alkyl group, or R3 forms a nitrogen-containing heterocyclic group with R1 and N,
- R1 is a C6-14 aryl group, a C4-14 heteroaryl group or a C2-24 alkylpolyoxyalkylene group,
- R2 is a C2-10 alkylene group, a C6-14 arylene group, a C4-14 heteroarylene group or a C2-24 polyoxyalkylene group, and
- the base is one or more bases selected from the group consisting of a heterocyclic aromatic amine, a non-nucleophilic strong base having a basicity (pKBH+) in acetonitrile of 20 or more and an inorganic base.
