The cyclo-(P4tBu3) synthon [Licyclo-(P4tBu3)}(thf)(tmeda)] (1) (thf = tetrahydrofuran, tmeda = N,N,N′,N′-tetramethylethane-1,2-diamine) is readily accessible in a one-pot synthesis from P4 and LitBu. The use of 1 as a cyclo-(P4tBu3) building block enables the rational synthesis of cyclo-(P4tBu3)-containing oligophosphanes, namely cyclo-(P4tBu3)}2 (2), cyclo-(P4tBu3)}2PtBu (3) and cyclo-(P4tBu3)}2CH2
环-(P 4 t Bu 3 ) 合成子[Li cyclo -(P 4 t Bu 3 )}(thf)(tmeda)] ( 1 ) (thf = 四氢呋喃, tmeda = N , N , N ', N ' -四甲基乙烷-1,2-二胺)在由 P 4和 Li t Bu 的一锅法合成中很容易获得。使用1作为cyclo -(P 4 t Bu 3 ) 结构单元能够合理合成cyclo -(P 4 t Bu3 )-含低聚膦,即环-(P 4 t Bu 3 )} 2 ( 2 )、环-(P 4 t Bu 3 )} 2 P t Bu ( 3 ) 和 cyclo -(P 4 t Bu 3 )} 2 CH 2 ( 4 ), C 3 v -对称磷腈 E环-(P 4 t Bu 3 )} 3 (E = Bi, Sb, As;5–7 ) 以及 AsCl cyclo -(P 4 t Bu 3 )} 2 ( 8 )。
