Title compounds I (M = Mo, R = Ph, 4-MeC6H4, 2-MeC6H4, 4-F3CC6H4; M = Cr, R = 4-F3CC6H4) were prepared by treating cycloheptatriene(tricarbonyl)molybdenum and -chromium with RLi; in Et2O at -60?followed by alkylation of the acylmetallate with Et3OBF4 in aqueous solution at 0? The crystal structure of I (M = Mo, R = 4-F3CC6H4) was determine
