the conformation of alinidine a new and specific bradycardic agent was studied using mndo method. it has been found that the rotation of both phenyl and imidazoline ring of this compound is restricted. of two possible isomers of irnidazoline ring, the one with nh in the cis position to allyl side chain is slightly more stable. on the other hand, the allyl group can rotate freely and at least si...

An eta2-peroxopalladium(II) complex, derived from dioxygen addition to Pd(IMes)2 (IMes = bis-1,3-di(2,4,6-trimethylphenyl)imidazoline-2-ylidene), has been isolated and characterized. Subsequent addition of HOAc to (IMes)2Pd(O2) yields the first example of a hydroperoxopalladium species derived from molecular oxygen. The characterization and reactivity studies of these complexes provide the most...
