Abstract

OH 84 (14)(a) Reaction conditions: 425 mg NaNO (5mmol) and 22 mg La (N0). 6 H 0 (0.05 mmol) were dissolved in 4 ml waterand 4 ml concen? rated HCl (d= 1.19). To3tfiis sglution were added 5 mmol of phenolic compound dissolved in 15 ml diethylether. After 10 minutes a yellow coloration appeared turning to red when the reaction was over. The reaction mixture was stirred for 3 to 8 h, at room temperature and then extracted with chloroform. ...
