Industrially important triaryl phosphites, traditionally prepared from PCl3, have been synthesized by a diphenyl diselenide-catalyzed one-step procedure involving white phosphorus and phenols, which provides a halogen- and transition metal-free way to these compounds. Subsequent oxidation of triaryl phosphites produces triaryl phosphates and triaryl thiophosphates. Phosphorotrithioates are also prepared efficiently from aromatic thiols and aliphatic thiols.

Herein, we describe the synthesis and resulting activity of a complex series of α-aminophosphonate diaryl esters as irreversible human neutrophil elastase inhibitors and their selectivity preference for human neutrophil elastase over several other serine proteases such as porcine pancreatic elastase, trypsin, and chymotrypsin. We synthesized and examined the inhibitory potency of several new simple Cbz-protected α- aminoalkylphosphonate diaryl esters that yielded several new HNE inhibitors, where one of the obtained compounds Cbz-ValP(OC6H 4-4-COOMe)2 displayed an apparent second-order inhibition value at 33,015 M-1 s-1.
Selective synthesis of organophosphites

Page 12-13, (2008/06/13)
Disclosed herein is a process for the selective synthesis of triorganophosphites intermediates, including chloridites and dichloridites, from PX3 (X=Cl, Br or I), alcoholos and triorganoamines where alcohol and triorganoamine are added either (a) separately and concurrently, or (b) alternating equimolar portions of amine and alcohol.
