Processes with Decrease in Coordination Number

Irregular Processes with Decrease in Coordination Number 

In principle, the permutational isomerization of TBP phosphorus can take place via an intermediate in which the phosphorus is tetraco-ordinated, and which is produced either thermally or under acid 

Other types of related irregular processes may be possible e.g., when there is a P-H ligand.122 

The occurrence of uncatalyzed irregular permutational isomerizations is inferred from observations which show that the difference in the stability between a molecule with pentacoordinated phosphorus and its 

The product of the reaction of benzil, C0H5.CO.CO.C9H5 with trisdimethylaminophosphine,126-128 [(CH8)2N]8P is obtained in two crystalline forms, one is a triaminodioxaphosphorane (110), and the other is a dipolar ion (111).
