In organometallic chemistry, a tuck-In complex usually refers to derivatives of Cp * ligands wherein a methyl group is deprotonated and the resulting methylene attaches to the metal. The C5-CH2-M angle is acute. The term "tucked-in" was coined to describe derivatives of organotungsten complexes.〔Cloke, G. N.; Green, J. C.; Green, M. H.; and Morley, C. P. "Metal Atom Synthesis and Photochemistry of Bis(q-pentamethylcyclopentadienyl)-tungsten Dihydride" ''J. Chem. Soc, Chem. Communication'' 1985 3430-3434. 〕 Although most "tucked-in" complexes are derived from Cp * ligands, other pi-bonded rings undergo similar reactions. ==Scope and bonding== The "tuck-in" process is related to ortho-metallation in the sense that it is an intramolecular cyclometallation.〔Hartwig, J. F. Organotransition Metal Chemistry, from Bonding to Catalysis; University Science Books: New York, 2010. ISBN 189138953X〕 Tuck-in complexes derived from Cp * ligands are derivatives of tetramethylfulvene, sometimes abbreviated Me4Fv. A variety of complexes are known for Me4Fv and related ligands. In these complexes, the Fv can serve as a 4-electron or as a 6-electron ligand. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tuck-in complex」の詳細全文を読む スポンサード リンク
