Description Application Gold Catalysts — 21st Century ′Gold Rush′ Yields olefins from secondary phosphates and thiophosphates. Using this reagent the etherification of alcohols with primary alkyl halides can be accomplished under mild conditions. Used to generate cationic rhodium catalysts from chlororhodium complexes for the hydrophosphination of acetylenes. Also employed as a catalyst for the preparation of silyl ethers by hydrosilylation of aldehydes. Packaging 1, 10, 25, 100 g in glass bottle
