Description / Table of Contents:
Reactions of tBu(Me3Si)P—P(Li)—P(tBu)2 with CH3Cl and 1,2-DibromoethanetBu(Me3Si)P—P(Li)—P(tBu)2 · 0.95 THF 1 with CH3Cl (-70°C) yields tBu(Me3Si)P—P = P(Me)(tBu)2 2 at -70°C, with 1,2-Dibromoethane tBu(Me3Si)P—PBr—P(tBu)2 3 (main product) and tBu(Me3Si)P—P=P(Br)tBu2 4. 3 eliminates Me3SiBr yielding the cyclotetraphosphane {tBuP—P[P(tBu)2]}2 5.
Notes:
tBu(Me3Si)P—P(Li)—P(tBu)2 · 0,95 THF 1 bildet mit CH3Cl bei -70°C das Ylid tBu(Me3Si)P—P=P(Me)(tBu)2 2, mit 1,2-Dibromethan tBu(Me3Si)P—PBr—P(tBu)2 3 (Hauptprodukt), sowie tBu(Me3Si)P—P=P(Br)tBu2 4. Aus 3 entsteht unter Abspaltung von Me3SiBr das Cyclotetraphosphan {tBuP—P[P(tBu)2]}2 5.
