Abstract: Bisphenols substantially free of by-products, are produced rapidly by reacting a phenol and a compound of the formulae: ##STR1## wherein R and R' are hydrogen, lower alkyl or aryl; X is lower alkoxy or the same as X'; Y is chlorine or the same as X; X' is aryloxy; Z is a 1,2- or 1,3-propylenedioxy (that may optionally carry hydroxy, lower alkyl or lower hydroxyalkyl substituents), or arylenedioxy radical; n is integer from three to nine; m is (n-1).

Abstract: Bisphenols, substantially free of by-products, are produced rapidly by reacting a phenol and a compound of the formula ##STR1## wherein R and R' are independently selected from the group consisting of hydrogen, lower alkyl or aryl; X is lower acyloxy; Y is lower alkoxy, aryloxy or the same as X; Z is the divalent radical ##STR2## wherein R" and R'" are selected from the same category as R and R', and n is an integer from 3 to 9; m=(n-1).
