Vaska's complex is the trivial name for the chemical compound trans -carbonylchlorobis (triphenylphosphine)iridium (I), which has the formula IrCl (CO) [P (C 6 H 5) 3] 2. This square planar diamagnetic organometallic complex consists of a central iridium atom bound to two mutually trans triphenylphosphine ligands, carbon monoxide and a chloride. 1 2 Som en av Nordens största varumärken inom håraccessoarer och bijouterier, erbjuder Complement ett spännande och moderiktigt sortiment. Här blandas klassiskt med nya trender tillsammans med bra funktioner och kvalitet. 3 4 Vaska’s complex (Figure 1), the discovery of which is credited to Angoletta in but named after the Estonian-American chemist Lauri Vaska after his extensive characterisation in , is an air-stable electron square planar iridium (I) complex that readily undergoes oxidative addition with a number of oxidants, acids and electrophiles. 5 The appropriate design of a ligand (L) in IrCl(CO)(L)2 (4) realized the efficient synthesis of π-conjugated enamines possessing hole-transport properties. The iridium complex with electron-withdrawing phosphorus ligands catalyzed the hydrosilylation of amides to the corresponding silylhemiaminals, which were transformed to the enamines by heat or by treatment with acids. High catalytic. 6 The in-situ-generated dimeric precursor [Ir(CO) 2 Cl] 2 reacts with four molar equivalents of the ligands 2-Ph 2 PC 6 H 4 COOMe (a) and 2-Ph 2 PC 6 H 4 OMe (b) to afford tetracoordinated complexes of the type trans-[Ir(CO)ClL 2] (1a, 1b), where L = a and b. 7 8 Complement. 9 Complement. 10
