Two routes to the title compounds are evaluated. First, a ca. 0.01 M CH2Cl2 solution of H3B·P((CH2)6CH=CH2)3 (1·BH3) is treated with 5 mol % of Grubbs' first generation catalyst (0 °C to reflux), followed by H2 (5 bar) and Wilkinson's catalyst (55 °C). Column chromatography affords H3B·P(n-C8H17)3 (1%), H3B·P((CH2)13CH2)(n-C8H17) (8%; see text for tie bars that indicate additional phosphorus-carbon
评价了两种制备标题化合物的途径。首先,一个ca。将H3B·P((
CH2)6CH = )3(1·
BH3)的0.01 M Cl2溶液用5 mol%的Grubbs第一代催化剂(0°C回流)处理,然后用H2(5 bar)和威尔
金森氏催化剂(55°C)。柱色谱法得到H3B·P(n-
C8H17)3(1%),H3B·P(( )13 )(n- )(8%;请参见有关指示其他
磷碳键的连接条的文字,以H3B·P(( )13 )(( )14)P(( )13 )· (6·2 ,10%),in,out-H3B·P(( )14)3P· (in,out-2·2 ,4%)和立体异构体(in,in / out,out)-2·2 (2%)。这些结构中的四个通过独立的合成得到验证。其次,将1,14-
十四烷二酸转化(还原,
溴化,Arbuzov反应,LiAlH
