Synthesis and reactivity of [(η⁶-[32](1,3)cyclophane)Mn(CO)3][BF<su b>4]

초록

The manganese cyclophane complex, [(eta(6)-[3(2)](1,3)cyclophane)Mn(CO)(3)][BF4] 2, was prepared by the reaction of [[3(2)](1,3) cyclophane] 1 with Mn(CO)(5)FBF3. Reaction of 2 with NaBH3CN yielded the cyclohexadienyl manganese complex [(eta(5)-6H-[3(2)](1,3)cyclophane)Mn(CO)(3)] 3. Interestingly, treatment of 3 with Mn(CO)(5)FBF3 gave the bis-manganese complex (eta(6), eta(5)-6H-[3(2)](1,3)cyclophane)[Mn(CO)(3)](2)[BF4] 4. When NaBH3CN was treated with 4, [(eta(5), eta(5)-6H,6'H-[3(2)](1,3)cyclophane)Mn(CO)(3)] 5 was isolated as yellow crystals. The structure of compounds 2 and 3 were determined by single-crystal X-ray crystallography. (C) 2004 Elsevier B.V. All rights reserved.
