Hydroxyphosphoric acids display the unique biological activities, and they have some attractive prospects as clinical drug moleculars. Herein, a new approach for the synthesis of γ-oxo-phosphonates (the precursor of hydroxyphosphoric acid) has been established through the semipinacol rearrangement tactic involved the photo-induced phosphorus radical process. Most important, this transformation is avoid of the external oxidants, and occurs very well under the sunlight irradiation, meanwhile the γ-oxo-phosphonate was easily derivatized to obtain γ-hydroxyphosphoric acid, thus highlights the synthesis value of this method.

A formally zwitterionic ruthenium catalyst precursor for the transfer hydrogenation of ketones that does not feature an ancillary ligand N-H dunctionality
Lundgren, Rylan J.,Rankin, Matthew A.,McDonald, Robert,Schatte, Gabriele,Stradiotto, Mark
, p. 4732 - 4735 (2008/02/10)
Fast and furious: Even without the assistance of an N-H donor ligand, the Ra complex shown in the scheme is a remarkably active precatalyst for the transfer hydrogenation of ketones in basic iPrOH (R,R′ = alkyl oraryl), providing near-quantitative yields within minutes and exhibiting consistently high turnover frequencies (104 to 105 h-1) for a diverse range of substrates. (Chemical Equation Presented).

The pKCsCHA values are reported for a number of symmetrically meta- and para-substituted diphenylmethanes.The pKCsCHA values for the meta series (Me, 33.8; OMe, 32.7; F, 29.9; CF3, 28.9; Ph, 32.3; H, 33.4) give a normal Hammett plot with ρ = 9.69.The para series (Me, 35.1; OMe,37.6; Ph, 30.8; NMe2, 38.6; SPh, 28.8; CN, 23.0; SO2Me, 22.4) do not fit attempted correlations with ?, the Yukawa-Tsuno modifications, or dual substituent parameter approaches.Electron-donating groups are more anion destabilizing than in other reference systems. "Amphoteric" substituents, those that stabilize both anions and cations (phenyl, thio, etc.), cause special problems in generalized correlations.
