Palladium-Catalyzed Hydroxycarbonylation of Aryl and Vinyl Halides or Triflates by Acetic Anhydride and Formate Anions ?

(Equation presented) The palladium-catalyzed reaction of aryl and vinyl halides or triflates in the presence of acetic anhydride and lithium formate as a condensed source of carbon monoxide provides an efficient simple route to the synthesis of the corresponding carboxylic acids. The reaction proceeds very smoothly under mild conditions and tolerates a wide range of functional groups, including ether, ketone, ester, and nitro groups. The presence of ortho substituents does not hamper the reaction. Labeled carbonyl products can be easily prepared by using H13COONa.

Structural isomers of aryl-substituted η3-propargyl complexes: η2-1-metalla(methylene)cyclopropene and η3-benzyl complexes

Hydride abstraction from C5Me5(CO)2Re (η2-PhC≡CCH2Ph) (1) gave a 3:1 mixture of η3-propargyl complex C5Me5(CO)2Re(η3- PhCH-C≡CPh)][BF4

Thermal isomerization of benzocyclobutene

Thermolysis of benzocyclobutene 13CH2, 99percent gives styrene labeled in the β (48percent), ortho (30percent), α (14percent), meta (4percent), and para (4percent) positions.The major labels (β and ortho) are consistent with a mechanism involving interconversions of the isomeric tolylmethylenes and the methylcycloheptatrienes.This mechanism also involves interconversion of o-tolylmethylene with o-xylylene and p-tolylmethylene with p-xylylene.A minor mechanism produces 25percent of styrene.This mechanism involves cleavage of the aryl carbon to the methylene carbon bond in benzocyclobutene followed by hydrogen transfer to produce styrene.Thermolysis of p-xylylene produced from paracyclophane gives styrene (55percent), p-xylene (31percent), benzocyclobutene (4percent), benzene (4percent), and toluene (3percent).Thermolysis of metacyclophane gives styrene (18percent), p-xylene (25percent), m-xylene (3percent), benzocyclobutene (1percent), benzene (7percent), and toluene (22percent).
