  A curable composition which contains mono- and poly-functional acrylate monomers and an acidic group-contain­ing acrylate monomer containing at least one acryloyloxy group per molecule, monofunctional acrylamide monomer, tri­alkylboron and/or partially oxidized product thereof. This composition shows excellent low-temperature curability around ordinary temperature and water-resistant adhesiveness, and exhibits excellent adhesiveness to teeth or dental alloys with less detrimental influences such as stimulation, thus being suited as binding agents for various composite resins. SUMMARY A curable composition is provided, comprising a monofunctional (meth)acrylate monomer, a poly functional (meth)acrylate monomer, a (meth)acrylate monomer containing an acidic group and at least one (meth)acryloyloxyl group in its molecule, a monofunctional (meth)acrylamide monomer, and a trialkylboron and/or a partial oxide thereof. The composition has improved low-temperature curability at approximately room temperature and water-­resistant adherence, and excellent adhesiveness to tooth substances including enamel and dentin and dental alloys, and gives no adverse influence of stimulation to dental pulp. Most preferably, the composition is used as a bonding agent for dental composite resins.

• An Investigation of Wall Effects in Microwave-Assisted Ring-Closing Metathesis and Cyclotrimerization Reactions
  作者：Doris Dallinger、Muhammed Irfan、Amra Suljanovic、C. Oliver Kappe

  日期：2010.8.6

  Challenging Ru-catalyzed ring-closing metathesis transformations leading to eight-membered-ring systems and Ni- or Co-catalyzed [2+2+2] cyclotrimerizations were evaluated at elevated temperatures applying microwave dielectric heating or conventional thermal heating in order to investigate the role of wall effects. All reactions were conducted in a dedicated reactor setup that allowed accurate internal reaction temperature measurements using fiber-optic probes for both types of heating modes. For ring-closing metathesis best results were achieved using an open vessel gas sparging protocol in 1,2-dichloroethane at reflux temperature (83 degrees C), while cyclotrimerizations were performed under sealed vessel conditions in toluene between 80 and 160 degrees C. For all studied transformations the results achieved in a single-mode microwave reactor could be reproduced by conventional heating in an oil bath by carefully matching the temperature profiles as close as possible during the entire heating and cooling cycle. In contrast to previous literature reports, no evidence that direct in-core microwave heating can increase catalyst lifetime by minimization or elimination of wall effects was obtained. At the same time, no indication for the involvement of nonthermal microwave effects in these homogeneous transition metal-catalyzed transformations was seen.
