WebClCH2C(O)Co(CO)4 (I) is prepd. by the reaction of ClCH2COCl with Na[Co(CO)4]. I readily decarbonylates to ClCH2Co(CO)4 (II). I is formed from II at .apprx.5 bar of CO pressure and room temp. or at 1 bar of CO by cooling to .apprx.-10 Deg in a reversible reaction. II with PPh3 gives ClCH2C(O)Co(CO)3PPh3 (III) that can be decarbonylated at 50 Deg to the … Web会员中心. vip福利社. vip免费专区. vip专属特权
