A method for synthesizing halogenated organic compounds, such as halogenated alkenyl group-containing and halogenated alkyl group-containing compounds having a heteroatom (e.g., O,N.S) coupled to a carbon atom of a halogenated alkenyl or halogenated alkyl group, involves reacting a halogenated olefin such as a chloro-substituted trifluoropropenyl compound with an active hydrogen-containing organic compound such as an alcohol (e.g., an aliphatic monoalcohol, aliphatic polyalcohol, or a phenolic compound), a primary amine, a secondary amine or a thiol.

A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have a hydrogen atom at the α-position, using a hydroperoxide as an oxidizer and an iodide salt as a catalyst precursor, thereby introducing an acyloxy group derived from the carboxylic acid into the α-position of the carbonyl compound.

A novel gypsum board having improved antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antifungal agent effective at inhibiting fungal growth. A preferred polymeric antifungal agent is polyDADMAC or polyTMMC. The novel gypsum board further comprises a non-polymeric antifungal agent comprising a fluorine-containing quaternary ammonium compound. Preferred non-polymeric ammonium compounds include Tetra-n-butylammonium fluoride and Tetraethylammonium fluoride. The polymeric antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antifungal agent may be encapsulated in a material or ionically associated with the polymeric antifungal agent to allow releases of the non-polymeric antifungal agent over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.

phenyl iodide and phenyl triflate to Pd(BINAP)2 (1) are reported. The products of the oxidative addition of phenyl trifluoromethanesulfonate to 1 in the presence of the primary amines n-octylamine and isoamylamine are the cationic aryl palladium(II) complexes [(BINAP)Pd(Ph)(H2NR)]OTf (2a,b), and the product of the oxidative addition of phenyl iodide to 1 is the phenylpalladium iodide (BINAP)Pd(Ph)I}
