Usage

General Description

(E)-α,β-Bis(benzoyloxy)stilbene, also known as benzilic acid dibenzoate, is a chemical compound consisting of two benzoyloxy groups attached to a stilbene backbone. It is commonly used as a photoinitiator in the polymer industry, particularly in UV-curing processes for coatings and adhesives. (E)-α,β-Bis(benzoyloxy)stilbene is known for its ability to initiate polymerization reactions when exposed to UV light, making it a valuable ingredient in the production of various polymer materials. Additionally, (E)-α,β-Bis(benzoyloxy)stilbene has also been studied for its potential use as a fluorescent probe in biological imaging, as well as for its anti-inflammatory and antioxidant properties. However, further research is needed to fully understand its potential applications in these areas.

Methylsulfinyl (Dimsyl) anion as umpolung catalyst for the chemoselective cross-benzoin reaction of α-diketones with aldehydes

The hitherto unreported ability of the methylsulfinyl carbanion (dimsyl anion) to generate acyl anion equivalents is described. The dimsyl anion, in fact, efficiently catalyzes chemoselective intermolecular cross-benzoin condensations of diaryl α-diketones (benzils) with various aromatic and aliphatic aldehydes to give the corresponding aryl-aryl and aryl-alkyl benzoin benzoates in an atom-economic fashion. The dimsyl anion acts as an environmentally friendly alternative to the toxic cyanide anion and it is obtained by in situ deprotonation of dimethyl sulfoxide (DMSO) solvent with a catalytic amount of a strong base, potassium tert-butoxide (t-BuOK) the optimal promoter. The assumption that the methylsulfinyl carbanion is the active catalyst in the title transformation is supported by electrospray ionization mass spectrometry (ESI-MS) experiments. Copyright

2,2-Dibutyl-1,3,2-dioxastannolens

Acyloins or their enediol carbonates (vinylene carbonates) react with dibutyltin oxide or dibutyltin dimethoxide to give 2,2-dibutyl-1,2,3-dioxastannolens . 119Sn N.m.r. and 119mSn Moessbauer spectra, and molecular weight measurements suggest that, in the solid state or in concentrated solution, the dioxastannolen (A) is associated, but the monomer is present in dilute solution.On heating, (A) decomposes into benzil and products which appear to be derived from dibutylstannylene, and it reacts with oxygen to give benzil and products derived from dibu- tyltin oxide.Acetyl chloride reacts to give cis-stilbene diacetate, but less reactive acylating agents (e.g. acetic anhydride or benzoyl chloride) give an increasing amount of the trans-diester and cyclic anhydrides (e.g. phthalic anhydride), and diacid chlorides (e.g. phosgene) give cyclic esters.
