Monomeric and polymeric triamino(imino)phosphoranes RR1N(R2R3N)P(NR4R5): NR6 [e.g. R = R3 = Me, R4 = R5 = Et, R1R2 = (CH2)3, R6 = CMe3; R = Et, R1R2 = R5R6 = (CH2)3, R3 = R4 = Me] were prepared from Cl3P:NCMe3 or PCl5. The monomers are inert, distillable liqs. with a basicity 1500-10,000 times that of DBU. Applications and advantages of these strong bases over common bases in elimination and condensation reactions is reported.
