Abstract
Thecyclo-(P4tBu3) synthon [Li{cyclo-(P4tBu3)}(thf)(tmeda)] (1) (thf = tetrahydrofuran, tmeda =N,N,N′,N′-tetramethylethane-1,2-diamine) is readily accessible in a one-pot synthesis from P4and LitBu. The use of1as acyclo-(P4tBu3) building block enables the rational synthesis ofcyclo-(P4tBu3)-containing oligophosphanes, namely {cyclo-(P4tBu3)}2(2), {cyclo-(P4tBu3)}2PtBu (3) and {cyclo-(P4tBu3)}2CH2(4),C3v-symmetric pnictaphosphanes E{cyclo-(P4tBu3)}3(E = Bi, Sb, As;5-7) as well as AsCl{cyclo-(P4tBu3)}2(8). Compounds5and6represent the first neutral homoleptic bismuthane and stibane that contain only bonds to phosphorus. All new compounds were isolated in moderate to good yields and fully characterised. The31P{1H} NMR spectral data of1,2,4, and8have been determined by automated line-shape analysis.File | Dimensione | Formato | |
