Description |
A pyridyl functionalized cyclodiphosphazane, cis-{(mu-(NBu)-Bu-t)P(OCH2C5H4N-o)}(2) (1) was synthesized by reacting pyridine-2-methanol with cis-{(mu-(NBu)-Bu-t)PCl}(2). The reactions of cis-{(m-NtBu) P(OCH2C5H4N-o)} 2 with chalcogenides in appropriate stoichiometry afforded both mono and bis-chalcogenides. The treatment of 1 with ML2Cl2 (M = Pd or Pt; L-2 = COD, (SMe2)(2)) in 1:1 molar ratios resulted in the formation of mononuclear complexes, [MCl2{(mu-(NBu)-Bu-t) P(OCH2C5H4N-o)}(2)] (8 M = Pd; 9 M = Pt), whereas the 1:2 reactions produced binuclear complexes [(MCl2)(2){(mu-(NBu)-Bu-t)P(OCH(2)C(5)H4N-o)}(2)] (10 M = Pd; 11 M = Pt). The reaction of 1 with [Ru(eta(6)-p-cymene)(mu-Cl)Cl](2) afforded [((eta(6)-p-cymene) RuCl2)(2){(mu-(NBu)-Bu-t) P(OCH2C5H4N-o)}(2)] (13). Reaction of [Rh(mu-Cl)(COD)](2) with 1 in a 1:2 molar ratio yielded the mononuclear complex, [{(CO) RhCl}(2){(m-(NBu)-Bu-t)P(OCH2C5H4N-o)}(2)] (14), while the 1:1 reaction of [Rh(mu-Cl)(CO)(2)](2) with 1 produced a binuclear complex [((CO)RhCl{(mu-(NBu)-Bu-t)P(OCH2C5H4N-o)}(2)] (15). The treatment of 1 with AuCl(SMe2) resulted in the formation of a binuclear complex [(AuCl)(2){(mu-(NBu)-Bu-t) P(OCH2C5H4N-o)}(2)] (16). The reaction of 1 with 2 equiv of CuBr gave coordination polymer [{Cu(mu-Br)} 2{(mu-(NBu)-Bu-t) P(OCH2C5H4N-o)}(2)](n) (17). The crystal structures of 5, 8-10, 13 and 17 were established by single-crystal X-ray diffraction studies. (C) 2014 Elsevier B.V. All rights reserved.
