Activation of 1,3,5-trimethyl-1,3,5-triazacyclohexane by Os3(CO)12 to form amidino [(MeN)2CH] cluster complexes
摘要:
Reaction of 1,3,5-trimethyl-1,3,5-triazacyclohexane [(MeNCH2)(3)] with Os-3(CO)(12) in refluxing toluene results in C-H and C-N bond activation of the (MeNCH2)(3) ligand to afford three amidino cluster complexes (mu-H)Os-3(CO)(10)[mu, eta(2)-CH(NMe)(2)] (1), (mu-H)Os-3(CO)(9)[mu(3),eta(2)-CH(NMe)(2)] (2), and Os-2(CO)(6)[mu,eta(2)-CH(NMe)(2)](2) (3). The controlled experiments show that thermolysis of 1 yields 2. and heating 2 in the presence of (MeNCH2)(3) ligand produces 3. The molecular structures of I and 3 have been determined by an X-ray diffraction study. (C) 2004 Elsevier B.V. All rights reserved.
