diphosphine, (PhCH 2 ) 2 PCH 2 CH 2 P(CH 2 Ph) 2 . Successive reactions with cis -1,4-dichloro-2-butene and LiAlH 4 give in turn the macrocyclic tetraphosphonium salt and then the 16-membered tert-phosphino-containing macrocyclicligand. A series of new manganesecomplexes MnLX 2 (X Cl, Br, I and NCS; L = 16-membered tert-phosphino-containing macrocycle) has been prepared and characterized.
摘要通过将三苄基膦与亚乙基二溴结合,合成了具有16元叔膦基的大环化合物,得到盐[(PhCH 2)3 P + CH 2 CH 2 p +(CH 2 Ph)3] 2 Br-,用氢化铝锂处理得到二膦,(PhCH 2)2 PCH 2 CH 2 P(CH 2 Ph)2。与顺式-1,4-二氯-2-丁烯和LiAlH 4的连续反应依次得到大环四phosph盐,然后得到16元含叔膦基的大环配体。已制备并表征了一系列新的锰配合物MnLX 2(XCl,Br,I和NCS; L = 16元含叔膦基大环化合物)。
