In water, metallic palladium was found to catalyze the deep oxidation of a wide variety of functional organics by dioxygen at 80-90°C in the presence of carbon monoxide or dihydrogen. Several classes of organic compounds were examined: benzene, phenol and substituted phenols, nitro and halo organics, organophosphorus, and organosulfur compounds. In every case, deep oxidation to carbon monoxide, carbon dioxide, and water occurred in high yields, resulting in up to several hundred turnovers over a 24 h period. For substrates susceptible to hydrogenation, the conversions were generally higher with dihydrogen than with carbon monoxide. For organophosphorus compounds, the system presents the first examples of catalytic cleavage of phosphorus - alkyl bonds.

Paragraph 0040; 0041, (2017/03/14)
The invention discloses a method for preparing dimethyl hypophosphite, first, the halogenated methane and methyl dimethyl phosphite according to mol ratio of 0.1-10:100 mixed, 90-150 °C reaction under 4-6h, be dimethyl phosphinic acid methyl ester; and then the the dimethyl phosphinic acid methyl ester mix with deionized water, the 80-120 °C hydrolysis reaction under acidic conditions 6-8h, be dimethyl phosphinic acid; soluble salt of the metal with the dimethyl phosphinic acid mixing, reaction to obtain the precipitate, then post-processed to obtain dimethyl hypophosphite; the metal as Al, Zn, Ti, Ca, mg or Fe. The invention also discloses the method the prepared dimethyl hypophosphite, has higher phosphorus content, will be applied to the engineering plastic, especially in glass fiber reinforced nylon and glass fiber reinforced polyester will obtain better fire retardant effect.

, p. 119 - 129 (2013/02/23)
An efficient synthesis of a phosphinate analogue of the anti-tumour phosphate di-ester perifosine is described (6 steps and 50% overall yield). The two phosphorus-carbon bonds in the perifosine analogue were prepared by sequential double radical hydrophosphinylation processes. This is the first example of a phosphinate analogue of perifosine, designed to be resistant to hydrolysis by phospholipid-metabolizing enzymes. The Royal Society of Chemistry.

Synthesis of alkyl phosphinic acids from silyl phosphonites and alkyl halides
Boyd, E. Andrew,Regan, Andrew C.,James, Keith
, p. 4223 - 4226 (2007/10/02)
Mono- and di-substituted phosphinic acids have been synthesised in a one-pot reaction, by the addition of alkyl halides to silyl phosphonites, under mild and flexible conditions.
