A variety of organophosphates are synthesized from n-BuLi-triggered, (additional) solvent-free reactions of diethyl phosphite with both activated/unactivated ketones and aldehydes preferably at room temperature via phospha-Brook rearrangement. We could successfully synthesize the naphthylic/allylic phosphates using this approach.

An efficient approach to the benzylation of arenes has been developed. The reactions described provide straightforward access to diarylmethanes through Pd-catalyzed coupling of benzylic phosphates with arylsilanes in good to excellent yields. The reaction tolerates a wide range of functionalities such as halide, alkoxyl, and nitro groups.
Nucleophilic addition to carbonyl compounds, competition between hard (amine) and soft (phosphite) nucleophile
Gancarz, Roman
, p. 10627 - 10632 (2007/10/02)
In the Kabachnik Fields reaction mixture, two nucleophiles: dialkyl phosphite and the amine compete for the electrophilic carbonyl compound. Reaction mixture composition studies, kinetic studies as well as theoretical calculations, indicate that the softe
UNEXPECTED PRODUCTS IN A KABACHNIK-FIELDS SYNTHESIS OF AMINOPHOSPHONATES
Gancarz, Roman
, p. 59 - 64 (2007/10/02)
In a Kabachnik-Fields synthesis of aminophosphonates derived from aromatic ketones the formation of hydroxyphosphonates, their rearrangement to corresponding phosphates and amine promoted decomposition of the last, leads to a number of unexpected products, which in some cases could be the only products of reaction.Key words: 1-Aminophosphonates; 1-hydroxyphosphonates; Kabachnik-Fields reaction; phosphonate-phosphate rearrangement.
Direct Esterification of Phosphates with Various Halides and its Application to Synthesis of cAMP Alkyl Triesters
Furuta, Toshiaki,Torigai, Hiromi,Osawa, Tomoko,Iwamura, Michiko
, p. 3139 - 3142 (2007/10/02)
Esterification of phosphates with various halides, including acid chlorides, phosphoryl trichloride and chloride, was achieved in 57-99percent isolated yield using silver(I) oxide.The reaction was successfully applied to the preparation of phosphate triesters sensitive to acids and bases. cAMP benzyl esters were also prepared by this method.
