Bis-(triphenylphosphino)-cuprous borohydride C화학적 특성, 용도, 생산
제조 방법
Bis-(triphenylphosphino)-cuprous borohydride is prepared by adding Copper(I) Chloride to a stirring solution of 2 equiv of Triphenylphosphine in chloroform. Once the copper chloride is dissolved the mixture is treated with a suspension of Sodium Borohydride (1 equiv) in ethanol for at least 15 min to ensure complete reaction. The solution is washed with water and dried over anhydrous magnesium sulfate. Diethyl ether is added to precipitate the reagent as fine white needles (90% yield).
주요 응용
Bis-(triphenylphosphino)-cuprous borohydride selectively reduces acyl chlorides to aldehydes, tosyl and triphenylsulfonyl hydrazones to alkanes, aldehydes and ketones to alcohols, and aromatic azides to anilines.
