Alkaline and alkaline earth metals

Abstract

Advances made during the calendar year 2011 relating to the coordination and inorganic chemistry of the elements of Groups 1 and 2 are summarised in this non-critical review. Coverage concentrates on topics centred around the synthesis, and applications of coordination and organometallic compounds of these elements. HighlightsThe isolation and reaction chemistry of kinetically-stabilised Group 2 species in which the alkaline earth centre exists in a formal +1 oxidation state has received intense international attention while interest in the potential of alkaline earth complexes as benign and inexpensive reagents for catalysis has continued to develop. LithiumA review of the resting-state structures of organocuprates determined using X-ray crystallography has appeared. 1 The electronic stability of s-block benzylates and di-and tri-phenylmethanide derivatives has been reviewed. 2 Reactions of the lithium boryl LiB(DippNCHQCHNDipp) with organohalides (RX) giving RB(DippNCHQCHNDipp) have been studied using DFT calculations. 3 Group 14 donor ligands An X-ray diffraction analysis of tetrareduced corannulene, C 20 H 10 4À , has confirmed the formation of a sandwich-type supramolecular aggregate in which five Li + ions are sandwiched between the two tetrareduced corannulene decks. 4 A combined experimental and DFT study has predicted that benzyl anions with strong p-withdrawing groups in the meta position have low energy diradical or triplet electronic states. 5 A lithium complex of an abnormal carbene with the composition [H 3 BC{{N(2, Pr 2 )C 6 H 3 } 2 )CHCLi(THF) 3 }] has been synthesised by lithiation of the NHC borane adduct. 6 Diastereomeric oxazolinylaziridines (R,R)-9 and (R,S)-9 have been regioselectively lithiated at the a-position with respect to the oxazolinyl ring. 7 Computational studies of the carbolithiation of b-methylstyrene with

“…CMPO coordinates predominantly to the metal ions through the oxygens on the carbamoyl or phosphine oxide groups, while the latter is the most preferred [15,59]. Alkali ligand coordination chemistry is presented extensively in the literature, with the state of research being reviewed annually [60]. Cesium coordination numbers (c.n.)…”
