Title: Ching-Shang Sheng: Innovator in Phosphine Oxide Chemistry
Introduction
Ching-Shang Sheng is a notable inventor based in Longtan, Taiwan. He has made significant contributions to the field of chemistry, particularly in the development of bisbiphenylacylphosphine oxide. With a total of 3 patents to his name, Sheng's work showcases his innovative approach to chemical synthesis.
Latest Patents
One of Sheng's latest patents involves the synthesis of bisbiphenylacylphosphine oxide and its preparation method. The process begins with the preparation of 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene (CDOP) using 2-phenylphenol. This compound is then esterified to synthesize 6-methoxy-(6H)-dibenz[c,e][1,2]oxa-phosphorin (MDOP). Following this, acid chloride compounds are introduced to perform the Arbuzov reaction, leading to the synthesis of bisbiphenylacylphosphine oxide. The hydrolysis of CDOP results in the formation of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), which subsequently reacts with arylaldehyde to yield secondary alcohol. The final preparation of bisbiphenylacylphosphine oxide is achieved through oxidation of the secondary alcohol and a coupling reaction involving DOPO and acid chloride compounds, facilitated by a Lewis acid catalyst.
