A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.

Paragraph 0102, (2016/10/07)
PROBLEM TO BE SOLVED: To provide: a (meth)acrylate-based polymerizable monomer which allows compatibility with various materials to be easily secured and provides a small value of (polymerization shrinkage rate)/(hardness of a cured product); and a material using the same. SOLUTION: The present invention provides a polymerizable monomer represented by general formula (1), a composition using the same, a curable composition and a resin member. [X is a divalent group; Y and Z are (meth)acroyloxy-L-OCHR1- (R1 is H or a C1-6 alkyl group as a monovalent group; and L is a hydrocarbon group whose main chain has 2-50 carbon atoms); Ar1 and Ar2 are aromatic groups; o and p are integers selected from the range from 1 to 3; and m and n are each 0 or 1. Here, if m=0, then Y and Ar2 are directly coupled; and if n=0, then Ar1 and Ar2 are directly coupled.] COPYRIGHT: (C)2016,JPO&INPIT
