2,6-di-t-butil-4-metilfenolün V A grubu elementleri ile oluşturduğu bileşiklerin sentezi ve özelliklerinin incelenmesi

Abstract

In the recent years, t-butyl substitued phenols whichare used as antioxidants in food and polymer industry,have been studied with a growing interest. Due to thesimilarity of the phosphorus derivatives of these kindsof the phenols to some models (phosphates) in biologicalsystems, 2,6-di-t-butyl-4-methylphenoxyphosphorus compounds(11,111) have been obtained from lithium phenoxideand phosphorus chlorides, t-butyl and triphenylmethylderivatives of the compound-II have also been prepared.On the investigations of the ESR spectra of the compoundsinvolving P-Cl bonds (III,V,VIII), it was seenthat the phenoxy radicals were generated due to the interactionsof them with L2Bz in toluene at room temperature.
