Metal Cluster Phosphite Complexes

TRI- AND TETRANUCLEAR CARBONYL-RUTHENIUM CLUSTER COMPLEXES CONTAINING ISOCYANIDE, TERTIARY PHOSPHINE, AND PHOSPHITE LIGANDS. RADICAL ION-INITIATED SUBSTITUTION OF METAL CLUSTER CARBONYL COMPLEXES UNDER MILD CONDITIONS... 

While other /i5-C5H5 compounds (page 736) with lone pairs can be proton-ated,3 ferrocene has its electrons in more or less bonding orbitals and is therefore an exceedingly weak base, being protonated only by superacids. Many metal carbonyls and phosphine or phosphite complexes,4- including clusters,5 can be protonated, and in some cases the salts can be isolated Fe(CO)5+H+ FeH(CO)j Ni[P(OEt)3]4 + H + = NiH[P(OEt)3]J Ru(CO)3(PPh3)2 + H+ = [RuH(CO)3(PR3)2] +...
