Kereiakes, D.J. et al. (2003) Phase I drug and light dose-escalation trial of motexafin lutetium and far red light activation (phototherapy) in subjects with coronary artery disease undergoing percutaneous coronary intervention and stent deployment procedural and long-term results, Circulation 108, 1310-1315. 

Similar ortfo-metallation products have been obtained from reactions of (775 7]1-CsMe4SiMe2NBut) Y(CH2SiMe3)(THF) with anisole and 3- and 4-methylanisole.290 Both the lutetium and ytterbium alkyl complexes were subjected to hydrogenolysis with dihydrogen or with phenylsilane in pentane at room temperature to give the... 

Lutetium is the last element in the lanthanide series. It has a completely filled 4f shell. As such, it has been the subject of intense study. In lanthanides, participation of 4f electrons in bonding is suggested and generally accepted as a... 

In this article, we will begin with an overview of the structures of binary rare-earth halides, RXz (with R being a cation of a rare-earth element, scandium, yttrium, lanthanum and cerium through lutetium and X a halide ion). Because binary halides were the subject of several excellent reviews, also in this handbook (Haschke 1979, Eick 1994), they will be mentioned only briefly. 

Lutetium-176 is radioactive and subject to branched decay by P emission, mostly to Hf, though approximately 3 1% decays to Yb. However, the latter can be disregarded because of the long half-life of Lu. Thus, the decay scheme of interest is... 

The lanthanide elements comprise lanthanum and the 14 elements (cerium to lutetium) that follow lanthanum in the periodic table. Frequently, the terms lanthanides and lanthanons are used as synonyms for the rare earth elements (REEs), although strictly the REEs comprise the lanthanides and also yttrium, which together with gadolinium, the subject of Chap. 29, is omitted from this chapter. As in many accounts of the chemistry of the lanthanides, will be used as the collective chemical symbol for the trivalent cations. 

This review will be limited to certain thermodynamic properties of gaseous species of the elements yttrium, scandium, and lanthanum to lutetium. The dissociation enthalpies and enthalpies of formation are the two quantities which are evaluated and tabulated for all the species considered here. There have been two recent reviews by Gingerich (1980a, 1985) on this subject and should be referred to for literature references. In this review, the values reported in the literature have been recalculated in a large number of cases using newer data for reference systems.
