Scandium complexes amine oxides

CCC (1987) contains a section on sulfoxides, amide, amine oxides, and related ligands that have sections on phosphine oxides and arsine oxides.159 Phosphine and arsine oxide complexes of yttrium and the lanthanides were highlighted in CCC (1987).1 Scandium and yttrium phosphine oxide complexes have been reinvestigated and characterized by multinuclear NMR and X-ray... 

Scandium complexes, 1059-1116 alkoxides, 1065 amides, 1062,1066 amine oxides, 1065 amines, 1060 amino acids, 1066 aromatic amines, 1061 arsenic compounds, 1065 2,2 -bipyridyl, 1061... 

Asymmetric 1,3-dipolar cycloaddition reaction of AT-benzylidenebenzyl-amine AT-oxide to 3-(( )-2-butenoyl)-l,3-oxazolidin-2-one was catalyzed by BlNOL-BOX-scandium complexes to give isoxazolidine in high yield with high enantioselectivity (111). La(lll)-aryloxide-PYBOX complexes were reported as enantioselective catalysts for direct Mannich-type reactions (112). 

Amine A-oxides, phosphine oxides and other phosphoryl compounds and analogous arsenic derivatives, and sulfoxides all give well-defined complexes with scandium. In many cases, authors deal with several of these classes of ligand in the same paper, so it will be most convenient to consider them together here.
