Recent progress of η2-disilene and η2-disilylne mononuclear transition metal complexes and related complexes are summarized. Although examples for disilene-transition metal complexes are still limited for group 4, 6, 8, 10 and 11 metals, η2-disilene transition metals complexes have been synthesized by various synthetic methods and structural characteristics are well discussed by using X-ray diffraction analysis, 29Si NMR resonances and Dewar-Chatt-Duncanson model. Reactions of these complexes have been also investigated. Very recently, η2-disilyne-group 10 metal complexes have been synthesized. In addition, transition metal complexes with doubly-bonded silicon compounds such as silenes (R2SiCR'2), silanimines (R2SiNR'), silanones (R2SiO) and related doubly-bonded germanium and tin compounds as η2-ligands are briefly summarized.
