| Abstract: | Reactions of tBu(Me3Si)P? P(Li)? P(tBu)2 with CH3Cl and 1,2-Dibromoethane tBu(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 . |
| Keywords: | tBu(Me3Si)P?P P(Me)tBu2, tBu(Me3Si)P?P(Br)?P(tBu)2, tBu(Me3Si)P?P P(Br)tBu2, {tBuP?P[P(tBu)2]}2 from tBu(Me3Si)P?PLi?P(tBu)2 with MeCl or 1,2-Dibromoethane |
