Sx. Gu et al., A CONVENIENT METHOD OF META-DIRECTING NITRATION OF 3-SUBSTITUTED PHENOL BY LANTHANIDE(III) NITRATES, Synthetic communications, 27(16), 1997, pp. 2793-2797
Thirteen compounds of 3-substituted phenols ware nitrated by lanthanid
e(III) nitrates in a solution of ethyl acetate. Whether the substituen
ts were ortho-, para-directing groups or meta-directing groups, only o
ne kind nitrated product, 3-substituted-5-nitropenol, and its intermed
iate were obtained respectively.
