Abstract
SE DESVELA UN NUEVO PROCESO PARA LA FABRICACION DE FOSFITOS DE ARILO OBSTACULIZADOS UTILIZANDO DERIVADOS DEL MERCAPTOTIAZOL O DEL ACIDO DITIOCARBAMICO COMO CATALIZADORES. LOS FOSFITOS DE ARILO ALQUILO ORTOTERCIARIOS SE PRODUCEN POR LA REACCION DE UN TRIHALIDO DE FOSFORO CON UN COMPUESTO FENOLICO ALQUILO ORTOTERCIARIO EN PRESENCIA DEL CATALIZADOR ANTERIORMENTE MENCIONADO.
