Phosphonation of β-nitro-alkene with triethyl phosphite was achieved under microwave irradiation using CH2Cl2 as the solvent in the absence of catalyst with moderate to high yields (up to 90%). This method of formation of carbonphosphor bonds is simple, mild, convenient and effective. Synchronously, a number of vinylphosphonates derivatives were synthesized and evaluated biologically preliminary.
Cerium(IV)-induced nitration of cinnamic acids. Novel remote electrophilic substitution

The treatment of (E)-3,4-dimethoxycinnamic acid with ceric amonium nitrate in trifluoroacetic acid afforded (E)1,2-dimethoxy-4-nitro-5-(2-nitroethenyl)benzene in 79percent yield.The unusual ipso substitution of the carboxylic acid moiety by a nitro functional center illustrated a new reaction manifold of cerium(IV).Six cinnamic acids were examined to ascertain the generality of the transformation.The bidentate nitrato structure of the metal salt is believed to account for the nitrating ability of this system.
