The corresponding acrylates or methacrylates have been obtained in moderate or high yields by pyrolyzing tetrahydrofurfuryl cu-acetoxypropio-nates and the P-meth~ xyethyl~ and p-phenoxyethyl4 esters of a-acetoxyisobutyric acid. These results suggested that an ether linkage on the@-carbon of the alkyl group increases the thermal stability of esters; the present work was done to ascertain the correctness of this premise and to determine ...
