Phosphite esters may be used as reducing agents in more specialised cases. For example, triethylphosphite is known to reduce certain hydroperoxides to alcohols formed by autoxidation [7] (scheme). In this process the phosphite is converted to a phosphate ester. This reaction type is also utilized in the Wender Taxol total synthesis.
Khan at an event in 2012. Salman Khan is an Indian actor and producer, known for his work in Hindi films. He made his film debut with a brief role in Biwi Ho To Aisi (1988), before having his breakthrough with Sooraj Barjatya's blockbuster romance Maine Pyar Kiya (1989) that won him the Filmfare Award for Best Male Debut.

When aliphatic alcohols are used the HCl by-product can react with the phosphate esters to give organochlorides and a lower ester. O=P(OR) 3 + HCl → O=P(OR) 2 OH + RCl. This reaction is usually undesirable and is exacerbated by high reaction temperatures. It can be inhibited by the use of a base or the removal of HCl through sparging.
Trimethyl phosphite is an organophosphorus compound with the formula P(OCH 3) 3, often abbreviated P(OMe) 3.It is a colorless liquid with a highly pungent odor. It is the simplest phosphite ester and finds used as a ligand in organometallic chemistry and as a reagent in organic synthesis.

Any −OH groups on the phosphates in these ester molecules may lose H + ions to form anions, again depending on the pH in a solution. In the biochemistry of living organisms, there are many kinds of (mono)phosphate, diphosphate, and triphosphate compounds (essentially esters ), many of which play a significant role in metabolism such as ...
Initially, Amin Khan was supposed to do the film as the lead protagonist in place of Salman Shah, but he was opted out of this film by director Sohanur Rahman Sohan and producer Sukumar Ranjan Ghosh and the leading male role was eventually given to Salman Shah after it was turned down by actor Tauquir Ahmed and model Adil Hossain Nobel.
