The present invention relates to compounds capable of serving as moderators of human and mammalian appetite and as such provides a means for reducing body mass. The compounds of the present invention are selective against melanin concentrating hormone and do not have the pernicious side effects resulting from compounds which interact with other appetite related brain receptors.
aryl carboxyl radicals favor strongly competitive addition to arene pathways. Herein, we demonstrate a solution to this challenge: a charge-transfer complex of aryl carboxylate via n-π∗ and π-π interactions induces chemoselective decarboxylation to aryl radicals for general functionalization. Presumably, the triplet complex significantly slows the rate of second-order aryl carboxyl radical addition to

Insecticidal and acaricidal pyrethroid esters of formula residue is replaced by a hydroxy group or a leaving group readilv displaced bv carboxylate anions are also novel.
in which R is one of certain substituted cyclopropyl radicals, A and B are certain halo, haloalkyl, alkyl and alkoxy radicals and a and b are 0, 1, 2, 3, 4 or 5, are novel and may be included in insecticidal and acaricidal compositions and used for killing insects and acarids. They can be in cis or trans configuration.
