  Synthesis of Hemilabile P,N Ligands: ω-2-Pyridyl-n-alkylphosphines

  摘要：

  A series of P,N ligands of the general formula (2-py)-(CH2)(n)-PR2 (2-py: 2-pyridyl; R: i-Pr (n = 1, 4-7), Ph (n = 5-7)) 4a-g and 6a has been synthesized. Starting from 2-picoline (1), 2-(omega-chloroalkyl)pyridines 3a-d are prepared. The reactions of 3a-d with (i-Pr)(2)PLi and Ph2PLi, respectively, result in the title compounds 4a-g in up to 89% yield. Reaction of Cl-(CH2)(3)-P(i-Pr)(2) with 2-picolyllithium (2) is an alternative route to 4a. Additionally, P,P,N ligands 7a and 9 are synthesized by similar methods. All new compounds were fully characterized. The formation of cyclic pyridinium derivatives 5a and 5b from intramolecular SN reactions of 3a and 3b is discussed in detail.
