1,3,5-Tri(4-pentynyl)-1,3,5-triazacyclohexane (tptach), a 1,3,5-triazacyclohexane ligand with three pendant alkyne groups, was synthesized. The metal tricarbonyl adducts [Cr(CO)3(tptach)] and [Mo(CO)3(tptach)], featuring a tptach co-ordinated to the metal centre via only the three nitrogen atoms, were prepared by reaction of tptach with reactive sources of “M(CO)3”. The chromium trichloride adduct [CrCl3(tptach)] was synthesized in low yield via the reaction of tptach with [CrCl3(thf)3]. Structural studies of [CrCl3(tptach)] and another chromium trihalide–tach adduct, [CrBr3(tmtach)] (tmtach = 1,3,5-trimethyl-1,3,5-triazacyclohexane), were made.
1,3,5-三(4-戊炔基)-1,3,5-三氮杂
环己烷(ptach)是一种带有三个炔基的 1,3,5-三氮杂
环己烷配体。
金属三羰基加合物[Cr(CO)3(tptach)]和[Mo(CO)3(tptach)]是通过 tptach 与活性源 "M(CO)3 "反应制备的,其特点是 tptach 仅通过三个氮原子与
金属中心配位。
三氯化铬加合物[CrCl3(ptach)]是通过 tptach 与[CrCl3(thf)3]反应合成的,产量较低。对[CrCl3(tptach)]和另一种三卤化
