The cyclocarbonylation of isopropenyl acetate(1) to produce 2-methoxy-2,5,5-trimethyl-1,3-dioxolan-4-one(2) by use of palladium(II)-phoshine catalyst with methanol in benzene solution was studied at 100 degC under 200 atm of CO.Conversion of 1 up to 98percent and yield to 2 as high as 67percent were attained.

, (2014/03/21)
A polymer comprising recurring units derived from a (meth)acrylate monomer of tertiary ester type having branched alkyl on alicycle is used to form a resist composition. When subjected to exposure, PEB and organic solvent development, the resist composition is improved in dissolution contrast.
