The phosphaketene Ph3GePCO is shown to react with the phosphide KP(tBu)2 to generate the anion [Ph3GePC(O)P(tBu)2]− 1 . This species reacts with CH3I or ClGePh3 to give the dissymmetric diphospha-ureas (tBu)2PC(O)P(GePh3)(CH3) 2 and (Ph3Ge)2PC(O)P(tBu)2 3 respectively. Sequential treatment of 2 with a base and CH3I affords a route to (tBu)2PC(O)P(CH3)2 5 . These species are products of the first modular diphospha-urea synthesis. The subsequent thermal and photochemical reactivity of these species was also probed and described. 相似文献
