  摘要：

  The alkylation of (ArHNCH2CH2)(2)NH with RX [RX = MeI, (2-C5H4N)CH2Cl] under basic conditions gives (ArHNCH2CH2)(22)-NMe (Ar = 2,6-Me2C6H3 L1a, 2,4-Me2C6H3 L1b) and (ArHNCH2CH2)(2){(2-C5H4N)CH2N (Ar = 2,4,6-Me3C6H2 L2a, 2,4-Me2C6H3 L2b) in moderate yield, respectively. Alternatively, L1a and L1b can be accessed by the arylation (with Ar-Br) of (H2NCH2CH2)(2)NMe in the presence of a catalytic quantity of Pd-2(dba)(3). Treatment of L1 with CoCl2 in n-BuOH gave high-spin [{(ArHNCH2CH2)(2)NMe}CoCl2] (Ar = 2,6-Me2C6H3 1a, 2,4-Me2C6H3 1b) in good yield; no reaction occurred with FeCl2. The molecular structure of la reveals a distorted trigonal bipyramidal geometry with the L1a adopting a mer-configuration. Reaction of L2 with MCl2 affords the cobalt and iron complexes, [{ArNHCH2CH2}(2)(2-C5H4N)CH2}NMCl2] (M = Co, Ar = 2,4,6-Me3C6H2 2a, 2,4-Me2C6H3 2b; M = Fe, Ar = 2,4,6-Me3C6H2 3a, 2,4-Me2C6H3 3b); the octahedral frameworks in 2a and 3a are found to be considerably distorted with one of the two M-N(mesityl-substituted) distances noticeably elongated [M-N 2.597(4)-2.795(2) angstrom]; no such inequivalence is observed in solution at room temperature. On activation with methylaluminoxane, complexes 1a and 1b display some activity for the oligomerisation of ethylene. (c) 2005 Published by Elsevier Ltd.
