This work describes a base-mediated borylsilylation of benzylic ammonium salts to synthesize geminal silylboronates bearing benzylic proton under mild reaction conditions. Deaminative silylation of aryl ammonium salts was also achieved in the presence of

Substituted furans are prepared by the palladium-catalyzed reaction of propargylic tosylates with acylchromates. The reaction is initiated by the oxidative additiion of propagylic tosylates to palladium(O) complexes to give 1,2-propadienylpalladium(II) co

2-(4-N,N-dimethylaminophenyl) heterocycles are smoothly obtained from the photolysis of 4-chloro-N,N-dimethylaniline in acetonitrile in the presence of furan, pyrrole, thiophene and some of their methyl derivatives bearing a free α-position. With 2,5-dimethyl heterocycles the arylation occurs with equal efficiency in the β position. In the case of furan, when the irradiation is carried out in methanol, cis/trans 2-aryl-5-methoxy-2,5-dihydro adducts are obtained. The reaction is rationalized as involving heterolytic cleavage of the C-Cl bond in the triplet state of the aniline. The intermediacy of the thus formed triplet aryl cation explains the observed high regio- and chemo-selectivity of the process. (C) 2000 Elsevier Science Ltd.
