ABSTRACT

(4-Hydroxy-3,5- di-tert-butylphenyl)chloromethanediphenylchlorophosphonium chloride transforms into (4-hydroxy-3,5- di-tert-butylphenyl)chloromethanediphenylphosphine oxide by the interaction with trimethyl orthoformate in mild conditions (80˚С, 0.5 hr). Phosphine oxide obtained and initial phosphonium salt reaсt with trimethyl orthoformate in severe conditions (120-130˚С, 2.5-3.0 hrs) to form 4-(diphenylphosphinylmethylene)-2,6- di-tert-butylcyclohexa-diene-2,5-one. The latter interacts with N-nucleophilic reagents on 1,6-addition scheme.
