Semiempirical and ab initio quantum chemical computations indicate that the intermediate formed prior to the selectivity-determining methyl transfer step in the reaction between glycosides and trimethylaluminum is a strongly hydrogen-bonded equilibrium O'--H-C ---O-H'"C, which is proposed to be an i
Incorporation of trans-1,2-diphenylcyclopropane (1) and its 3,3-D2-isotopomer into the channels of a redox-active pentasil zeolite (Na-ZSM-5) resulted in the formation of exo,exo-1,3-diphenylallyl radical (2 β’ ) and its 2-D1 isotopomer, respectively. This conversion requires oxidation, ring opening,
Further studies have demonstrated that the site-specific hydrogen transfer process involved in the formation of the m Iz 145 anion of P-hydroxyamine pentafluoropropionate (PFP) derivatives observed under electron capture negative ion chemical ionization conditions occurs when the two functional grou
