Calculate Digit Verification of CAS Registry Number 74851-87:
(7*7)+(6*4)+(5*8)+(4*5)+(3*1)+(2*8)+(1*7)=159
159 % 10 = 9

SYNTHETIC STUDIES ON ASATONE-TYPE NEOLIGNANS OXIDATION OF 4-ALLYLPHENOLS WITH THALLIUM (III) NITRATE

Niwa, Masatake,Noda, Hitoshi,Kobayashi, Hiroki,Yamamura, Shosuke

, p. 85 - 88 (2007/10/02)

Oxidation of 4-allylphenols in MeOH has been carried out using thallium (III) nitrate to give two different types of reaction product.In the cases of 4-allylphenols with an electron-donating group (MeO), methoxylation takes place on the aromatic ring resulting in the formation of asatone-type compound as well as of 2,5-cyclohexadien-1-one.In the case of 4-allyl-2-methoxy-6-nitrophenol, however, the allyl group was attacked by the reagent to give three phenols.
