Organotitanium proves to be one of ideal organometallic candidates because of its low price, non-toxicity, diversified types, excellent chemo-, regio-and stereo-selectivities. The reactivity of organotitanium reagent could be easily controlled by ligands of central titanium atom. Recently, the coupling reactions of organotitanium reagent have attracted extensive attention. This review summerized recent progress in transiton metal-catalyzed coupling reactons of organotitanium reagents concerning their types.
