Abstract
Demetalation of (pi-allyl)[hydridotris(pyrazolyl)borato]molybdenum com plexes can be achieved via lactonization. A carboxylic acid moiety is installed via addition of methyl phenylsulfonylacetate enolate to a di ene-Mo(CO)(2)Tp complex, followed by desulfonylation and hydrolysis, s o that the subsequent lactonization can be effected by CO/NO+ exchange or with iodine to give decomplexed products from cyclic and acyclic c omplexes.
