[Cr(eta(6)-1,3,5-Me(3)C(6)H(3))(2)][E], where E = pcmcp, dbcp, or dbncp. Mo(eta(6)-arene)(2) derivatives (arene = toluene, 1,3,5-Me(3)C(6)H(3), 1,3,5-(i)Pr(3)C(6)H(3)) are oxidized to [Mo(eta(6)-arene)(2)](+) by pcmcpH. The crystal and molecular structures of [M(eta(6)-1,3,5-R(3)C(6)H(3))(2)][pcmcp] (M = Cr, R = Me; M = Mo, R = Me, (i)Pr) have been solved by X-ray single crystal diffraction.
M(eta(6)-arene)(2)种(M = Cr,芳烃= 1,3,5-Me(3)C(6)H(3); M = Mo,芳烃= 1,3,5 -Me(3)C(6)H(3),1,3,5-(i)Pr(3)C(6)H(3))已通过改良的Fischer-Hafner合成法或金属制得蒸气技术。Cr(eta(6)-1,3,5-Me(3)C(6)H(3))(2)与富烯衍生物五碳甲氧基环戊二烯(pcmcpH),1-苯甲酰基-6-羟基-6的反应-苯基富烯(dbcpH)或1-苯甲酰基-3-硝基-6-羟基-6-苯基富烯(dbncpH)随着二氢的释放和离子衍生物[Cr(eta(6)-1,3,5- Me(3)C(6)H(3))(2)] [E],其中E = pcmcp,dbcp或dbncp。Mo(eta(6)-arene)(2)衍生物(arene =甲苯,1,3,5-Me(3)C(6)H(3),1,3,5-(i)Pr(3)
