Amorphous-nonmetal—to—crystalline-metal transition in electrochromic iridium oxide films We report studies of sputtered iridium oxide films (SIROF's) by differential thermal analysis, evolved-gas analysis, scanning electron microscopy, x-ray diffraction, and electrical-conductivity measurements. SIROF's...
3.1 Allenes as Allylmetal Surrogates via Transfer Hydrogenation Although carbonyl tert-prenylation occurs efficiently upon iridium-catalyzed hydrogenation of 1,1-dimethylallene in the presence of aldehydes, attempted crotylations and allylations employing methylallene or allene gas, respectively, suffer from...
