    • A bisbiphenylacylphosphine oxide of formula (I) and its preparation method are provided. The formula of —Ar— is First, 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene (CDOP) is prepared by using 2-phenylphenol, and then is esterified to synthesize 6-methoxy-(6H)-dibenz[c,e][1,2]oxa-phosphorin (MDOP). Next, acid chloride compounds are added for performing the Arbuzov reaction to synthesize bisbiphenylacylphosphine oxide. CDOP is hydrolyzed to be derived into 9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide (DOPO), and then DOPO reacts with arylaldehyde to form secondary alcohol. Therefore, bisbiphenylacylphosphine oxide is prepared by using secondary alcohol under oxidation. Also, under a coupling reaction, DOPO reacts with the acid chloride compounds by using a Lewis acid as a catalyst to prepare bisbiphenylacylphosphine oxide.
    • 提供式(I)的双联苯酰基氧化膦及其制备方法。 -Ar-的配方是通过使用2-苯基苯酚制备10-氯-9,10-二氢-9-氧杂-10-磷杂菲(CDOP),然后酯化合成6-甲氧基 - (6H) - - 二苯并[c,e] [1,2]氧杂 - 磷杂(MDOP)。 接下来,加入酰氯化合物进行Arbuzov反应以合成双联苯基酰基氧化膦。 将CDOP水解成9,10-二氢-9-氧杂-10-磷杂蒽-10-氧化物(DOPO),然后DOPO与芳基醛反应形成仲醇。 因此,通过使用仲醇在氧化下制备双联苯基酰基氧化膦。 此外,在偶联反应中,DOPO通过使用路易斯酸作为催化剂与酰基氯化合物反应以制备双联苯基酰基氧化膦。
