Transesterification reactions yield bicyclic (caged) phosphite esters P(OCH2)3CCH2OH (1) and (P(OCH2)3CCH2)2O (2), and P(OCH2)3CCH2O2CR (R = Ph, 3; 4-tBuC6H4, 4; 4-O2NC6H4, 5; 3-pyridyl, 6; 4-pyridyl, 7; 1/2 p-C6H4, 8; 1/2 m-C6H4, 9; 1/3 1,3,5-C6H3, 10), which can act as ligands. Metal-bridged complexes and X-ray structures of 7, [(η5-MeCp)Mn(CO)2]2(μ-2)} (11), and [CuBr(2)]∞·MeCN (12) are reported
酯交换反应产生双环(笼型)亚磷酸酯P(OCH 2)3 CCH 2 OH(1)和(P(OCH 2)3 CCH 2)2 O(2),以及P(OCH 2)3 CCH 2 O 2 CR (R =苯基,3 ; 4-吨BUC 6 ħ 4,4 ; 4-O 2 NC 6 H ^ 4,5 ; 3-吡啶基,6 ; 4-吡啶基,7 ; 1/ 2 PC 6 H ^ 4,8 ; 1 / 2三菱商事6 ħ 4,9 ; 1 / 3 1,3,5-C 6 H ^ 3,10),其可作为配体起作用。金属桥连络合物和的X射线结构7,[(η 5 -MeCp)的Mn(CO)2 ] 2(μ- 2)} ...(11),和[溴化亚铜(2)] ∞ ·的MeCN(12)被报道。
