The cobalt catalyzed hydroaldoximation and hydrocyanooximation of unactivatedalkenes is reported. Secondary and tertiary aldoximes and oximonitriles are synthesized with excellent regioselectivity under mild conditions, and conversion of the products to valuable intermediates is documented. The reactions expand the arsenal of reductive carbon-carbon bond forming reactions as well as regioselective
Four-component coupling reactions between xanthogenates, alkenes, CO, and sulfonyl oxime ethers were studied. In the presence of hexabutylditin, working as a propagating radical reagent, the chain reaction proceeds, as expected, taking into account reagents polarities, affording the corresponding functionalized α-keto oximes. Although yields are modest, this rare one-pot four-component process is easy

Disclosed herein are compounds of the general Formula (I), and methods of synthesizing substituted bicyclo[1.1.1 jpentanes. The synthetic methods described herein use a [1.1.1]propellane, a Group VIII transition metal compound, a hydride source and a reagent that can contribute a substituent to form a substituted bicycIo[1.1.1 ]pentane, such as a compound of the general Formula (I).
Acylated oximeethers have been prepared by a three-component coupling reaction using alkyl allyl sulfone precursors, carbon monoxide, and phenylsulfonyloximeether derivatives under tin-free radicalreaction conditions.
