View all references due to the presence of a sheath of chemically inert oxygen atoms, which protect the central ion from undesired inner??sphere substitution reactions. For this reason, electron transfer with (K 5 CoW 12 O 40 · 3H 2 O) typically leads to selective reactions and clean chemistry. This advantage has encouraged us to continue our investigation of applications of (K 5 CoW 12 O 40 · 3H 2 O) in organic synthesis.1518. Habibi , MH , Tangestaninejad , S. ...
