An active, general, and long-lived palladium catalyst for Suzuki-Miyaura reactions of aryl and heteroaryl chlorides deactivated by steric hindrance, electron richness, and coordinating functional groups is reported. In reactions of arylbromide bearing two o-tert-butyl substituents, C(sp3)-H arylation of the tert-butyl group, rather than the Suzuki-Miyaura reaction, proceeded in excellent yield. The key to the success of the reactions was the development of biphenylene-substituted dicyclohexylruthenocenylphosphine (CyR-Phos) as a supporting ligand.

Palladium-catalyzed decarboxylative alkynylation of alpha-acyloxyketones triggered by C(sp3)?O bond cleavage is disclosed. The decarboxylation strategy featuring a neutral reaction condition enabled an unprecedent catalytic alkynylation of a ketone enolate. The reaction was applied to a variety of substrates, giving desired products in good yields. We successfully obtained X-ray crystallography of a new palladium?enolate intermediate that was synthesized by a reaction of [Pd(cod)(CH2TMS)2] with XPhos and alpha-acyloxyketone at room temperature, indicating facile C(sp3)?O bond disconnection.

A study has been made of the reductive carbonylation of 2,4-dinitrotoluene (2,4-DNT) to 2,4-diisocyanotoluene (2,4-TDI) with catalysis either by , in the presence of FeO3 and MoO3 or of Fe(MoO4)3 as cocatalysts, or by Pd0 complexes without cocatalysts.In the case of catalytic systems based upon the reaction can be carried out at about 200 deg C and under 200 atm of CO to produce 2,4-TDI with high conversions and acceptable selectivities.With Pd0 complexes as catalysts good conversions can be achieved at much lower temperatures (100-120 deg C) but with a low selectivity when a higher pressure of CO is used (300 atm or more).An investigation of the reductive cabonylation of nitrobenzene to phenylisocyanate as a model system, together with a study of the thermal stability of in the presence of CO, has provided evidence that the actual active catalyst could be a reduced (probably zerovalent) form of palladium stabilised by the nitroaromatic substrate or by some of the products formed from it as ligands.
