RhCl3-catalyzed hydroboration of alkenyl nitriles
(Elsevier: Tetrahedron Letters, 2003-08-11)
RhCl3-promoted hydroboration-oxidation reactions of representative alkenyl nitriles have been carried out. Carbanion of acetonitrile is formed from the carbon&unknown;carbon heterolytic bond breaking in allyl cyanide during ...
Efficient hydride-assisted isomerization of alkenes via rhodium catalysis
(The American Chemical Society: Organometallics, 2003-04-14)
We find that alkenes isomerize rapidly in the presence of catalytic amounts of a hydroborating reagent and a rhodium compound. The hydroborating reagent is apparently responsible for the in situ generation of a metal hydride ...
Transition-metal-promoted hydroboration of alkenes: a unique reversal of regioselectivity
(The American Chemical Society: The Journal of Organic Chemistry, 2002-04-19)
When hydroboration of 1-octene is carried out in the presence of catalytic amounts of rhodium trichloride followed by the usual oxidation (hydrogen peroxide in aqueous alkali), only minor proportions of 1-octanol (2.4%) ...
Adenosine dialdehyde analogs I: regioselective synthesis of adenosine monoaldehydes
(Elsevier: Bioorganic and Medicinal Chemistry Letters, 1996-06-18)
Selective borohydride reduction of adenosine dialdehyde (1) gave the known adenosine 2'-monoaldehyde (2). Reaction of 1 with N,N'-diphenylethylenediamine, followed by reduction and deblocking gave adenosine 3'-monoaldehyde ...
Reaction of 2,4-dinitrobenzenesulfenyl chloride with quadricyclene
(The American Chemical Society: The Journal of Organic Chemistry, 1982-04-09)
The treatment of quadricyclene with 2,4-dinitrobenzenesulfenyl chloride has been reinvestigated and chloro adducts 1-A and 2b-A as well as acetates 4a-A, 4b-A, 6, and 7 have been obtained. Establishing 2b-A with endo-chloride ...
Stereochemistry and mechanism of ionic cyclopropane ring cleavage by arenesulfenyl chloride addenda in quadricyclene systems
(The American Chemical Society: The Journal of Organic Chemistry, 1975-10-17)
Addition of benzenesulfenyl chloride to quadricyclenedicarboxylic acid (la) and to the corresponding dimethyl ester (1b) gave adducts [exo-5-chloro-endo-3-phenylthiotricyclo[2.2.1.0^2,6]heptane-2,exo-3-dicarboxylic acid ...
Ionic addition mechanism investigation. Determination of deuterated nortricyclyl alcohol stereochemistry
(The American Chemical Society: The Journal of Organic Chemistry, 1973-02-09)
Stereochemistry and mechanisms of cyclopropane ring cleavage. Addition of hydrogen chloride to tetracyclo[3.2.0.02,7.04,6]heptane-1,5-dicarboxylic acid (quadricyclenedicarboxylic acid)
(The American Chemical Society: The Journal of Organic Chemistry, 1971-09-24)
Addition of hydrogen chloride to tetracyc10[3.2.0.0^2,7.0^4,6] heptane-l15-dicarboxylic acid (1, quadricyclenedicarboxylic acid) under various conditions results in two products, exo-5-chlorotricyclo[2.2,1.0^2,6] ...
Stereochemistry and mechanisms of the addition of deuterium chloride to bicyclo[2.2.1]heptadiene (norbornadiene) and to tetracyclo[3.2.02,7.04,6]heptane (quadricyclene)
(The American Chemical Society: The Journal of Organic Chemistry, 1971-09-24)
Addition of hydrogen chloride and deuterium chloride to bicyclo [2.2.1] heptadiene (I, norbornadiene) results in (unlabeled and labeled, respectively) exo-dehydronorbornyl chloride (III) and nortricyclyl chloride (IV). The ...
