Synthesis of Selenium-containing para-Phenylenediamines: Novel Antidegradants for Natural Rubber
Parr, William J. E.
, p. 3002 - 3007 (2007/10/02)
The synthesis of novel N,N'-substituted para-phenylenediamines bearing side-chains containing one or two monoselenide linkages is described.Reductive alkylation of para-phenylenediamines with oxoselenides using sodium cyanoborohydride in methanol gives good to high yields of these compounds.Compounds containing one selenide linkage react with 3 mol equivalents of ozone, and those containing two selenide linkages react with 4 mol equivalents of ozone, compared to only 2 mol equivalents of ozone in the case of N-isopropyl-N'-phenyl-p-phenylenediamine.Synthetic routes to the oxoselenides required as precursors are described.
