Synthesis of ribosylated 1,2,3‐triazole derivatives
Heteroatom Chemistry - Tập 14 Số 6 - Trang 487-490 - 2003
AbstractRibosylated 1,2,3‐triazole 4 and 5 were synthesized in moderate yields
by the reaction of aroyl‐substituted heterocyclic ketene aminals 1 or 2 with
2,3,5‐tri‐O‐benzoyl‐β‐D‐ribofuranosyl azide (3). Their structures were
determined by elemental analyses and spectroscopic methods. © 2003 Wiley

Organometallic chemistry of silver and copper N‐heterocyclic carbene complexes
Heteroatom Chemistry - Tập 13 Số 6 - Trang 534-539 - 2002
AbstractThe only stable organometallic carbene complexes of silver and copper
are those of N‐heterocyclic carbenes, since formally these robust divalent
carbon ligands bind only by a σ donor interaction to the metal. A survey of the
range of complexes that have now been reported is presented. © 2002 Wiley

Synthesis of [Zn(ΙΙ)BHPPDAH] as New Heterogeneous Catalyst without Being Immobilized on Any Support and Applied for Mannich Reaction
Heteroatom Chemistry - Tập 24 Số 5 - Trang 372-383 - 2013
ABSTRACTIn this paper, a novel heterogeneous complex of zinc with
N,N‐bis(2‐hydroxyphenyl)pyridine‐2,6‐dicarboxamide(BHPPDAH) was synthesized. The
catalyst was found to be a highly effective catalyst for the three‐component
coupling reactions of aldehydes, alkynes, and amines (A3 coupling) via C–H
activation. The reactions could be applied to both aromatic and aliphatic
aldehydes and alkynes. Near...
Reinvestigation on the halogenation of 1,1,2,3,4,5‐hexaphenylstannole
Heteroatom Chemistry - Tập 12 Số 5 - Trang 349-353 - 2001
AbstractHalogenation of 1,1,2,3,4,5‐hexaphenylstannole was reinvestigated.
Reaction of the stannole with 2 equiv. of bromine gave
1‐bromo‐4‐dibromophenylstannyl‐1,2,3,4‐tetraphenyl‐1,3‐butadiene. Reaction of
the stannole with iodine gave similar results. Reaction of the stannole with 1
equiv. of bromine or iodine afforded
1‐halo‐4‐halodiphenylstannyl‐1,2,3,4‐tetraphenyl‐1,3‐butadiene, resulting fr...
Microwave‐assisted solid‐phase synthesis of 2,4,5‐triaryl imidazoles in solventless system: An improved protocol
Heteroatom Chemistry - Tập 17 Số 7 - Trang 699-702 - 2006
AbstractThe solventless microwave‐assisted synthesis of 2,4,5‐triaryl imidazoles
from 1,2‐diphenylethandione or 2‐hydroxy‐1,2‐diphenylethanone in the presence of
NH4OAc/NaHSO4 supported onto silica gel under microwave irradiation is reported.

MnCl2‐Promoted synthesis of quinoxaline derivatives at room temperature
Heteroatom Chemistry - Tập 19 Số 2 - Trang 218-220 - 2008
AbstractMnCl2 efficiently catalyzes the condensation of o‐phenylenediamine
derivatives with 1,2‐diketones at room temperature to afford the corresponding
quinoxaline derivatives in high yields. © 2008 Wiley Periodicals, Inc.

Green synthesis and cytotoxic activity of dibenzyl α‐hydroxyphosphonates and α‐hydroxyphosphonic acids
Heteroatom Chemistry - Tập 29 Số 4 - 2018
AbstractA series of dibenzyl α‐hydroxyphosphonates and the corresponding
α‐hydroxyphosphonic acids, mostly new compounds, have been synthesized. The
dibenzyl α‐hydroxyphosphonates have been obtained in the Pudovik reaction of
substituted benzaldehydes and dibenzyl phosphite in the presence of
triethylamine as the catalyst. The amount of the solvent was minimized during
the reaction, and the workup...
