Sulfided heterogeneous, bimetallic Ru/Mo catalysts derived from mixtures of Ru 3 (CO) 12 (or RuCl 3 ) and a molybdenum heteropolyanion: The reactions of ethanol with tetrahydroquinoline
(John Wiley & Sons Ltd., 1992-09)
Efforts have been made to develop Ru/Mo bimetallic catalyst systems for hydrodenitrogenation (HDN) of tetrahydroquinoline (THQ). In the course of these studies, it was discovered that in ethanol, under hydrogen and in the ...
Preparation of highly functionalized 3,4-disubstituted cyclobutene-1,2-diones using functionalized zinc-copper organometallics
(Elsevier, 1992)
The selective substitution reactions of the zinc-copper reagents with 3,4-dichlorocyclobutene-1,2-dione 2 allows to prepare a variety of new functionalized symmetrical and mixed 2,4-disubstituted cyclobutene-1,2-diones of ...
cis-2-Tri-n-butylstannylvinyl cuprates: a new synthon for the cis-1,2-ethene dianion
(Elsevier, 1992-01-01)
Conjugate additions of lower order and higher order cyano cuprates containing the cis-2-tri-n-butylstannylvinyl group to cycloalkenones have been studied. The higher order cuprates were more reactive towards hindered enones ...
Decreased formation of inositol trisphosphate in Madin-Darby canine kidney cells under conditions of [beta]-glucosidase inhibition
(Elsevier, 1992-02-01)
Recent work has demonstrated the enhancement of hormone-stimulated inositol trisphosphate formation in renal epithelial cells under conditions of glucosylceramide depletion. The role of glucosylceramide metabolism was ...
Thermodynamics of ammonium halopallidates I. Heat capacity and thermodynamic properties of (NH4)2PdCl6 at temperatures from 6 K to 350 K
(Elsevier, 1992-09)
The heat capacity of ammonium hexachloropallidate (NH4)2PdCl6 was measured at temperatures from 6 K to 350 K by adiabatic calorimetry. The heat-capacity curve is smooth and without anomalies. It rises rapidly from T0 to T ...

Interpretation of dynamic scattering experiments on ternary polymer mixtures
(Elsevier, 1992)
The dynamics of a ternary polymer mixture consisting of either homopolymers A and B, or diblock copolymers A-B, in a matrix of homopolymers C, is studied using the random phase approximation and assuming incompressibility. ...
Synthesis and characterization of molybdenum nitride hydrodenitrogenation catalysts
(Elsevier, 1992-06-30)
Details concerning the relationships between the structural, chemical and catalytic properties of Mo nitrides have been elucidated. A series of Mo nitride catalysts were prepared by the temperature programmed reaction of ...
New mannose-specific lectins from garlic (Allium sativum) and ramsons (Allium ursinum) bulbs
(Elsevier, 1992-05-22)
Two new mannose-binding lectins were isolated from garlic (Allium sativum, ASA) and ramsons (Allium ursinum, AUA) bulbs, of the family Alliaceae, by affinity chromatography on immobilized mannose. The carbohydrate-binding ...
Preparation and Reactivity of Polyfunctional Zinc and Copper Organometallics Bearing Sulfur Functionalities
(Elsevier, 1992)
Iodomethylthiobenzoate 5 and [alpha]-chloroalkyl phenyl sulfides 6 were found to insert zinc dust in THF under very mild conditions (10-25 [deg]C, 0.5-2 h) leading to zinc [alpha]-thioorganometallics. After a transmetallation ...
