Basicity and conformational analysis of carbamoylmethylphosphoryl compounds
摘要:
The basicity in nitromethane of carbamoylmethylphosphoryl compounds (CMP), RR' P(O)CHR''' C(O)NR2", containing different substituents at the phosphorus or nitrogen atoms and in the methylene bridge and binary reactants (CMP)2X, where X = (CH2)5 or p-CH2C6H4CH2, was investigated. The values of pK(a) are linearly correlated with SIGMA-sigma-P, the constant of the substituents at the phosphorus atom. Conformational analysis of CMP and tetraphenylmethylenediphosphine dioxides substituted in the methylene bridge showed that bulky substituents reduce the population of complexing conformations.

second [Hg(L)]+ unit. Additional examples of this general reactivity/structure pattern are reported herein. In contrast, in Hg(II) complexes of two CMPO derivatives, in which the amide N-atom is functionalized with a 2-methylpyridine group, the trifunctional phosphine oxides are observed to behave as neutral ligands forming complexes (L′)Hg (NO3)2.
