The regioselective photochemical rearrangement of alpha-[PN(t)Bu](4).
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).
