CR, CO, AND MN ARENE PI-COMPLEXES BASED ON DIPHENYLMETHANE AND TRIPHENYLMETHANE

The interaction of Ph2CH2 and Ph3CH with Cr(CO)6, Co2(CO)8, and Mn(CO) 5BF4 leads to mononuclear LCr(CO)3, LCo4(CO)9, and [LMn(CO)3]BF4 pi-ar ene complexes. Similarly, LCr(CO)3Co4(CO)9 and [LCr(CO)3Mn(CO)3]BF4 he teroaromatic derivatives are obtained from LCr(CO)3 complexes, whereas LCo4(CO)9 complexes afford L[Co4(CO)9]2 bicluster derivatives.
