An electrochemical method to achieve carbamoylphosphonates from phosphoramides and alcohols via P-H oxidation and functionalization by using n-Bu4NI as a catalyst is reported. A series of carbamoylphosphonates were obtained with good to excellent yields under mild reaction conditions. The electrochemical reaction is carried out under constant current electrolysis, with the alcohol being used as a solvent and a substrate, and is an attractive green synthesis method.

A series of carbamoylphosphonates (1-11) have been synthesised by the direct reaction of isocyanates with dialkyl phosphites catalysed by sodium metal The compounds have been characterised on the basis of their analytical and spectral data. Their thermal
The Schmidt reaction of dialkyl acylphosphonates

The scope of the Schmidt rearrangement of ketones has been extended to dialkyl acylphosphonates (11a-11l). Surprisingly, it was found that 11a-11d and 11g, in which the acyl moiety was benzoyl alone or benzoyl bearing an electron-attracting or mildly electron-releasing substituent, yielded an overwhelming portion of products resulting from C-to-N migration of the aryl group (N-arylcarbamoylphosphonates, 12, and N-arylformamides, 15). Contrariwise, the arenecarbonylphosphonates, which carry a powerful electron-releasing p-alkoxy group, yielded products resulting from phosphonate group migration from C to N or elimination (dialkyl N-arenecarbonylphosphoramidates, 13, and arenecarbonitriles, 17, respectively). These counterintuitive results are rationalized by application of the concept of "degree of electron demand" to this area of intramolecular rearrangements. The possible existence of an additional pathway for the Schmidt rearrangement, involving protonation of the iminodiazonium ion, is proposed.
Synthesis of organophosphorus compounds via silyl esters of phosphorous acids

The addition of trimethylsilyloxy phosphorus (III)derivatives generated in situ to imines at room temperature provides a mild selective and high yielding route to α-aminoalkylphosphorate and α-aminoalkylphenylphosphinate esters. Isocyanates and carbodiimides react similarly to give phosphonoureas and phosphonoguarnidines respectively aldehydes and ketones are much less reactive and cyanides are inert.
