  Center-to-propeller and propeller-to-propeller stereocontrol in a series of macrobicyclic tri-λ5-phosphazenes

  摘要：

  Center-to-propeller stereocontrol in a family of macrobicyclic, double-propeller shaped tri-lambda(5)-triphosphazenes remains constant in the upper tribenzylamine fragment as the size of the pivotal group at the lower tris(phosphane) fragment is gradually increased. In contrast the propeller-to-propeller stereocontrol diminishes as a result of the increasing conformational lability in the lower hemisphere. (C) 2007 Elsevier Ltd. All rights reserved.

  Ring slippage of the indenyl occurs upon dissolution of the complexes [η5-IndM(CO)2L2]BF4 (M=Mo of W; L=NCMe or dimethylformamide) in an excess of L, to give [(η3-Ind)M(CO)2L3]Bf4. Other ring-slipped complexes synthesized are [(η3-Ind)Mo(CO)2L3]BF4 (L3=HC(pz)3, [HB(pz)3]−, Me3tacn or en(NCMe)}). Addition of NCMe or an excess of L failed to give ring slippage in [η5-IndMo(CO)2L2]BF4 (L2=bipy, dppe
