摘要：

All products of the reaction of [tBu2P]2PLi 1 with 1,2-dibromoethane 2 were investigated. Already at -70-degrees-C tBu2P-P=P(Br)tBu2 3 as main product and [tBu2P]2PBr 4 are formed. Only with an excess of 1 also [tBu2P]P-P[P(tBu)2]2 5 is obtained. Warming of a pure solution of 3 in toluene from -70-degrees-C to -30-degrees-C leads to 4, and at 20-degrees-C tBu2PBr and the cyclophosphanes P4[P(tBu)2]4 and P3[P(tBu)2]3 are observed, 5 does not result from 3, it's rather a byproduct from the reaction of 1 with 4. Also the ylide 3 and 1 yields 5.
