Latest Patents

One of Lin's latest patents is focused on bisbiphenylacylphosphine oxide and its preparation method. This invention involves a complex synthesis process that begins with the preparation of 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene (CDOP) using 2-phenylphenol. Following this, CDOP is esterified to synthesize 6-methoxy-(6H)-dibenz[c,e][1,2]oxa-phosphorin (MDOP). The process continues with the addition of acid chloride compounds to perform the Arbuzov reaction, ultimately leading to the synthesis of bisbiphenylacylphosphine oxide. The method also includes hydrolysis of CDOP to derive 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), which reacts with arylaldehyde to form secondary alcohol. The final steps involve oxidation of the secondary alcohol and a coupling reaction with acid chloride compounds using a Lewis acid as a catalyst.
