and 1·(thf)2, to be unstable in solution. Our strategy to circumvent the fragility of these compounds involved the use of phosphinoboranes HPPh2·BH3 and HPPh2·B(C6F5)3 instead of HPPh2. This allowed for the synthesis of [Carb}AePPh2·BH3}] (Ae = Ba, 2; Ca, 3), [Carb}Ca(H3B)2PPh2}·(thf)] (4), [Carb}BaPPh2·B(C6F5)3}] (5), [Carb}BaO(B(C6F5)3)CH2CH2CH2CH2PPh2}·thf] (6), [BaO(B(C6F5)3)CH2CH2CH2CH2PPh2}2·(thf)1
[Carb}BaPPh 2 ] ( 1 ) 的尝试合成表明,这种磷化钡及其 thf 加合物1 ·thf 和1 ·(thf) 2在溶液中不稳定。我们规避这些化合物脆弱性的策略涉及使用膦硼烷HPPh 2 ·BH 3和HPPh 2 ·B(C 6 F 5 ) 3代替HPPh 2 。 这样就可以合成 [Carb}AePPh 2 ·BH 3 }] (Ae = Ba, 2 ; Ca, 3 )、[Carb}Ca(H 3 B) 2 PPh 2 }·(thf) ] ( 4 ), [Carb}BaPPh 2 ·B(C 6 F 5 ) 3 }] ( 5 ), [Carb}BaO(B(C 6 F 5 ) 3 )CH 2 CH 2 CH 2 CH 2 PPh 2 }·thf] ( 6 ), [BaO(B(C 6 F 5 ) 3 )CH 2 CH 2 CH 2 CH 2 PPh 2 } 2 ·(thf)
