PREPARATION OF 1,3-DIOLS BY METALATION-HYDROBORATION OF ALKYNES A 1,2-HYDROGEN MIGRATION FROM BORON TO CARBON

Metalation of a series of 1- and 2-alkynes with subsequent treatment with diborane and oxidation gave 1,3-diols exclusively.Deuteroboration of the lithiated acetylenes established the occurrence of a displacement of one of the B atoms by deuterium in gem-diboronated compounds.Hydroboration of several acetylenes and acetylides was also studied.

Acid-catalyzed reduction of ketones by an NADH model compound and the relation with acid-catalyzed photoinduced electron-transfer reactions

Various ketones are readily reduced by an acid-stable NADH model compound, 10-methylacridan (AcrH2), in the presence of perchloric acid in acetonitrile.Rates of the acid-catalyzed reduction of ketones by unprotonated AcrH2 are well correlated with rates of the acid-catalyzed photoinduced electron-transfer reactions from the excited state of 2+ to the ketones.

THE EFFECT OF PHENYL SUBSTITUENTS ON ELIMINATION STEREOCHEMISTRY: A MECHANISTIC MANIFOLD IN ALKOXIDE PROMOTED DECOMPOSITION OF 1-PHENYL-1-PROPYLTRIMETHYLAMMONIUM ION

Reactions of the positionally isomeric 1-phenyl-1-propyl (I) and 1-phenyl-2-propyltrimethylammonium (II) ions with CH3OK - CH3OH, t-C4H9OK - t-C4H9OH and t-C4H9OK - C6H6 systems have been investigated with aid of the deuterated analogues erythro-2-D-I, threo-2-D-I, 1-D-I and threo-1-D-II.At least five mechanistic components (anti-β-elimination, syn-β-elimination, α',β-elimination, Sommelet-Hauser rearrangement and SN2 substitution) have been found to participate in the reaction of the quaternary compound I, in proportions varying greatly with base-solvent combination.The corresponding reactions of the isomeric compound II proceeded in a more simple manner, withount the intervention of ylide pathways in the olefin as well as in the amine formation.The stereochemistry of β-elimination determined for the two phenyl-substituted 'onium compounds has been compared with that reported previously for structurally related aliphatic analogues.The "anomalously" low propensity for syn-elimination as well as the "anomalously" high values of trans/cis-olefin rations in anti-elimination stigmatizing the presence of phenyl substituents are proposed to originate from a lack of base-approach hindrance in the reaction.
