Title: Substituted dipyrromethanes and their preparation

New chemical compounds, bis(pyrrol-2-yl)halocarbylmethanes, also known as meso-halocarbyl dipyrromethanes, are made by recting pyrrole in either of two reaction schemes. Once such scheme converts pyrrole through an intermediate, a halocarbyl carbonyl pyrrole, to a [2-(1-hydroxyl-1-hydro-1-halocarbyl)pyrrole], and then converts the latter to the desired halocarbyldipyrromethane; the last step in this scheme is a novel and useful method in itself. The other such sequence converts pyrrole, by reaction with a halocarbyl aldehyde, directly to the desired halocarbyl dipyrromethane.
