Abstract:
The photochemical dyotropic (two-bond shift) rearrangement of the phosphazane cage alpha-[PN(t)Bu](4) (alpha) into the isomer beta-[PN(t)Bu](4) (beta) occurs via a multi-step radical mechanism; the structures of the alpha and beta isomers are directly analogous to isovalent alpha- and beta-As(4)S(4) and P(4)S(4).

Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
Regioselectivity of Electrophilic Additions to Alkenes: Markovnikov's Rule
The hydrohalogenation of an unsymmetrical alkene can yield two haloalkane products, depending on which vinylic carbon takes up the halogen. However, one product usually predominates, where hydrogen adds to the vinylic carbon bearing the...
