Submitted by KENNETH J. REIMER and ALAN SHAVERt Checked by MICHAEL H. QUICK and ROBERT J. ANGELICI  

MnCl(CO)s begins to precipitate. After complete addition, the reaction mixture is allowed to warm to room temperature and is then stirred for 4 hours. The yellow precipitate is filtered in air and washed several times with carbon tetrachloride. The yield of crude product is 4.04 g (86%). The compound is contaminated with only small amounts of [MnCl(C0)4] 2 and white insoluble material. These impurities are negligible and usually no further purification is undertaken. If pure MnCl(CO)s is required, it is easily obtained by sublimation (40°/0.1 torr, yield 65%) [based on Mn2(CO)io]. Anal. Calcd. for MnCl(CO)s C, 26.06 Cl, 15.39. Found C, 26.08 Cl, 15.44.
