Host-guest metal fluoride systems

Mixed metal fluoride systems where the cations of the minor component can principally substitute cations of the major component in the lattice therefore open an easy way to

Many MgF2/Mp3 systems are reported with HS-Mgp2 being the major component, the host, and the guest metal fluoride amounts to up to 30%. Such systems, which should be rather considered as solid solutions and which might be doped systems, have been reported with Pe , Ga , In , and Cr as guest cations [13-15]. Por Mgp2 the 

however, worth noting that the simple solid Fe +/Mgp2 catalyst was rather active for Priedel-Crafts benzoylation (Equation (3.11)) and acylation as well as alkylation (Equation (3.12)).
