Reactions of cyclomanganated complexes with carbon disulfide: routes to η2-aryldithiocarboxylate-Mn(CO)4 complexes and to the trithiocarbonate complex (μ3-CS3)2Mn4(CO)16
摘要:
Reaction of cyclomanganated aryl ketones with CS2 proceeds with insertion into the Mn-C bond to give eta(2)-dithiocarboxylato-Mn(CO)(4) compounds. With other cyclomanganated substrates such as that from Ph3P=S and also with Mn-2(CO)(10), CS2 gives (mu(3)-CS3)(2)Mn-4(CO)(16) with bridging trithiocarbonate ligands. (C) 2002 Elsevier Science B.V.

Reaction of PhCH2Mn(CO)(5) with 1,4-di-aryl-1-aza-1,3-butadienes gave substituted pyrrolinonyl rings which Were eta(4)-coordinated to a Mn(CO)(3) group. These are formed by intramolecular CO insertion into a (non-isolated) cyclomanganated intermediate, followed by cyclisation. Other unsaturated reagents (PhC drop CH, CH2 = CHCOOMe, PhNCO) gave products arising from insertion of these, including a structurally characterised tri-aryl-eta(5)-azacyclohexadienyl-Mn(CO)(3) complex from the reaction with the alkyne.
