This invention relates to a novel solution phase process for the preparation of amide, carbamate, and sulfonamide combinatorial libraries. These libraries have utility for drug discovery and are used to form wellplate components of novel assay kits.
Photographic materials which comprise novel color photographic couplers are provided. The silver halide color photographic material is improved in sharpness and prevention against the mixing of colors.

An acid chloride can be produced at a high yield from a primary alcohol having a polyfluoroalkyl group and one methylene group by (1) a method in which RfCH2OH (wherein Rf is a polyfluoroalkyl group) is reacted with chlorine to produce RfCOCl, (2) a method in which RfCHO is reacted with chlorine to produce RfCOCl, and (3) a method for producing an acid chloride comprising (a) a step in which an aldehyde (RfCHO) is formed from an alcohol (RfCH2OH), (b) a step in which a monochloroester (RfCOOCHClRf) is formed from the aldehyde and an acid chloride (RfCOCl), and (c) a step in which the acid chloride (RfCOCl) is formed from the monochloroester.
