In geometry, a deltoidal hexecontahedron (also sometimes called a trapezoidal hexecontahedron, a strombic hexecontahedron, or a tetragonal hexacontahedron) is a Catalan solid which is the dual polyhedron of the rhombicosidodecahedron, an Archimedean solid. It is one of six Catalan solids to not have a Hamiltonian path among its vertices. It is topologically identical to the nonconvex rhombic hexecontahedron. (Wikipedia).

Epoxidation of Alkenes - DMDO, mCPBA, & NaOCl (IOC 26)
In this episode, I discuss the epoxidation of electron-rich and electron-poor olefins, using peracids, DMDO, hydrogen peroxide, and sodium hypochlorite (NaOCl). *Note: for some reason, I didn't manage to pronounce MMPP correctly; it's full name is magnesium monoperoxyphthalate. *WARNING*
