Preparation of Silole Derivatives and Their Reactions with Dimethyl Acetylenedicarboxylate

Reaction of silone derivatives such as 1,1,3,4-tetramethylsilole (1) and 2,3-dimethyl-5-silaspironona-1,3-diene (2) with dimethyl acetylenedicarboxylate (DMADC) were investigated.It was found that the reactions of 1 and 2 with DMADC in toluene gave 7-membered ring componds; trimethyl 7-methoxy-3,3,3',4'-tetramethyl-6-oxa-3-sila-1,2-benzocyclohepta-1,4-diene-4,5,6'-tricarboxylate and trimethyl 5-methoxy-8,9-dimethylspiro-2,3,6-tricarboxylate, respectively.

Highly-functionalized arene synthesis based on palladium on carbon-catalyzed aqueous dehydrogenation of cyclohexadienes and cyclohexenes

Transition metal-catalyzed dehydrogenation is a clean oxidation method requiring no additional oxidants. We have accomplished a heterogeneous Pd/C-catalyzed aqueous dehydrogenation of 1,4-cyclohexadienes and cyclohexenes to give the corresponding highly-functionalized arenes. Furthermore, various arenes could be efficiently constructed in a one-pot manner via a Diels-Alder reaction and the following dehydrogenation.

A short synthetic route to a hybrid molecule benzosultine-sulfone via [2+2+2] cyclotrimerization using Mo(CO)6

Here, we report an improved and short synthetic route to benzosultine-sulfone via [2+2+2] cyclotrimerization as a key step, starting with dipropargyl ether and 1,4-dibromo-2-butyne with an overall yield of 16%.

Flapping viscosity probe that shows polarity-independent ratiometric fluorescence

A variety of fluorescent molecular viscosity probes have been widely used for mapping the local viscosity in cells and for monitoring the microenvironments in materials. However, their viscosity-sensing structural design still relies strongly on molecular

Diels-Alder reactions: The effects of catalyst on the addition reaction

Abstract The reaction between 2,3-dimethyl-1,3-butadiene and dimethyl 7-oxabicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate is efficiently achieved with small amounts of catalyst, i.e. phenol, AcOH, nafion, and β-cyclodextrin. Exo-diastereoselective cycloa

A contribution to the direct observation of transient phosphanylidene complexes [RP=W(CO)5] (R: Me, Ph): A revisited approach to their electronic structure by UV-photoelectron spectroscopy

An original approach involving a coupling in the gas phase between flash vacuum thermolysis (FVT) and UV-photoelectron spectroscopy (UV-PES) allowed the transient terminal electrophilic phosphanylidene complex [MeP=W(CO)5] to be characterized; this is the first direct observation of this P-Me derivative. This approach also permitted the electronic structure of [PhP=W(CO)5] to be revisited and confirmed the results obtained with the methylated analogues. In contrast, [p-NC-C6H4P=W(CO) 5] proved to be too reactive to be detected under our experimental conditions. These [RP=W(CO)5] phosphanylidene complexes (R: Me, Ph) were identified by their ionization potentials, which are real fingerprints . These experimental data, supported by density functional calculations, give an overall electronic cartography of these transient species. For generation in the gas phase of these phosphanylidene complexes, the thermal degradation of two kinds of precursors were investigated. The joint experimental/theoretical approach allowed us to conclude that phosphanorbornadiene complexes are more suitable precursors than phosphirane complexes. Copyright

Design and synthesis of benzosultine-sulfone as a o -Xylylene precursor via cross-enyne metathesis and rongalite: Further expansion to polycyclics via regioselective diels-alder reaction

Benzosultine-sulfone 5 has been prepared as a o-xylylene or o-quinodimethane precursor by utilization of rongalite. Thermal activation of this hybrid molecule 5 has resulted a new sulfone-based building block 6. Building block 5 is a suitable precursor for the synthesis of unsymmetrically functionalized polycyclics through Diels-Alder (DA) chemistry. The dibromosulfone 24 and benzosultine-sulfone 5 has also been used for the synthesis of various sulfone based unnatural α-amino acid (AAA) derivatives.
