[reaction: see text] An efficient electrochemical synthesis of 5-methylene-1,3-oxazolidin-2-ones (2a-h) from acetylenic amines (1a-h) and carbon dioxide has been achieved by direct electrolysis solution MeCN Et4NPF6 containing the amine, with subsequent CO2 bubbling heating. The yields vary good to excellent, conditions are mild, use toxic harmful chemicals catalysts is avoided.

Abstract The intrinsic chemistry of imidazolium‐based room‐temperature ionic liquids, related to the acidity C‐2 imidazolium cation, can be modified via cathodic cleavage C‐2/hydrogen bond. N‐Heterocyclic carbenes, electrogenerated by electrolysis are stable bases that strong enough deprotonate bromoamides 1a–k yielding azetidin‐2‐one ring C‐3/C4 bond formation. electrosynthesis β‐lactams 2a–k has been achieved under mild conditions, elevated yields and avoiding use toxic, volatile,...
Despite the well-known favorable chemical and mechanical properties of titanium-based materials for orthopedic dental applications, poor osseointegration implants, bacteria adhesion, excessive inflammatory response from host remain major problems to be solved. Here, antioxidant anti-inflammatory enzyme-like abilities ceria (CeOx) were coupled advantageous features titanium nanotubes (TiNTs). Cost-effective fast methods, such as electrochemical anodization drop casting, used build active...
Biopolymers have gained importance in various sectors such as biomedical, automotive and agriculture, well single‐use food packaging. However, to make them competitive with traditional plastics, biopolymers require certain modifications, including the addition of plasticizers and/or blending other macromolecules. This study aims develop biodegradable films using starch blended chitosan, plasticized by choline chloride [Ch][Cl], acetate [Ch][OAc], an ionic liquid derived from choline. The...

Abstract N ‐Heterocyclic carbenes (NHCs), generated by electrochemical reduction under galvanostatic control of 1,3‐dialkylimidazolium‐based ionic liquids, were employed as catalysts in transesterification reactions the parent, room temperature liquids (RTILs) solvents, without utilisation any volatile organic solvent or base. The reaction between isopropenyl ethyl acetate and an alcohol (not efficient absence catalyst) was induced presence electrogenerated NHC, which seems to assist proton...
Time of flight secondary ion mass spectrometry (ToF‐SIMS) has become a fundamental analytical technique in cultural heritage studies to obtain the identification and distribution organic components present artworks. A sample taken from soldier's golden shield decoration fresco Vela della Castità (San Francesco Lower Basilica, Assisi) was studied. The metal leaves for gilding on wall paintings are usually applied using an oil‐resin mordant as adhesive. In this work, inorganic compounds used...
Despite the significant contribution of titanium and its alloys for hard tissue regenerative medicine, some major issues remain to be solved. Implants' long-term stability is threatened by poor osseointegration. Moreover, bacterial adhesion excessive inflammatory response are also considered in design a device intended integrated into human body. Here, cerium mixed oxide (CeOx) coating was realized on pristine nanotubular-structured Ti Ti6Al4V surfaces using simple layer-by-layer...
