The choice of the precursors should be done taking into account its ligands, since they may cooperate in the emitter synthesis. Three different functions are clearly pointed out in the revised procedures: the ligands of the starting compounds can direct the selectivity of competitive ruptures of sigma-bonds of the chromophores, without having direct participation in the activation; on the contrary, they can directly participate in the generation of a ligand, being a part of the new coordinated group; and the ligands can also act as internal base in sigma-bond heterolytic activation reactions. In addition, the ability of the polyhydrides OsH6((PPr3)-Pr-i)(2) and IrH5((PPr3)-Pr-i)(2) to activate C-H bonds is pointed out as one of the determining factors of the success in many cases. info:eu-repo/grantAgreement/ES/DGA/E06-20R info:eu-repo/grantAgreement/ES/MICINN/PID2020-115286GB-I00/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/RED2018-102387-T info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.551 2021 CHEMISTRY, INORGANIC & NUCLEAR 23 / 46 = 0.5 2021 Q2 T2 0.553 2021 Inorganic Chemistry 2021 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Esteruelas Rodrigo, MA (orcid)0000-0002-4829-7590 López de Lama, AM Universidad de Zaragoza (orcid)0000-0001-7183-4975 2010 760 Universidad de Zaragoza Dpto.
