Using a frustrated Lewis pair approach, the 1,1-bis-(C(6)F(5))(2)BOB(C(6)F(5))(2) is shown to bind CO(2) in a monodentate fashion, while the bis-boranes (X(2)B)(2)C[double bond, length as m-dash]CMe(2) (X = Cl, C(6)F(5)) give bidentate chelation of CO(2) affording unique heterocycles.

An Isolable dialkylsilylene reacts with dihydrogen in the presence of a small amount of a conventional Lewis acid (BPh3, BEt3) or a base (PPh3, PEt3, NPh3, NEt3) at low temperatures in a hydrocarbon s...
Carbon monoxide is reduced by HB(C6F5)2 at the Mes2PCH2CH2B(C6F5)2 P/B FLP template to give the respective FLP stabilized (η(2)-formyl)borane product 2. This adds sulfur dioxide by insertion of a SO ...
A bulky substituted stannane Ar*SnH3 (Ar*=2,6-(2',4',6'-triisopropylphenyl)phenyl) was treated with the well-known frustrated Lewis pair (FLP) PtBu3 /B(C6 F5 )3 in varying stoichiometries. To some deg...
Hydroboration of dimesitylvinylphosphane with bis[3,5-bis(trifluoromethyl)phenyl]borane [HB(Fxyl)2 ] gave the intramolecular ethylene-bridged P/B frustrated Lewis pair (FLP) Mes2 PCH2 CH2 B(Fxyl)2 . T...
Inspired by the zwitterion species generated from the splitting of H2 by frustrated Lewis pairs, we put forward a novel frustrated Lewis pair by the combination of H(δ-) and H(δ+) incorporated Lewis...
We aim to test our method for measuring chemosensitivity (the ventilatory response to a change in carbon dioxide), which uses sinusoidal carbon dioxide stimuli. Hypotheses: - Ca...
Carbon dioxide insufflation during colonoscopy significantly reduces discomfort (pain, bloating and flatulence) after the procedure. So far, it has not been studied in inflammatory bowel d...
The purpose of this study is to determine if blowing carbon dioxide into the surgical field during open-heart surgery to displace retained chest cavity air from the atmosphere will decreas...
Endovascular repair of infrarenal abdominal aortic aneurysms (AAA) requires a contrast agent to identify the vascular anatomy and placement of the stent graft. Iodine contrast has traditi...
Carbon dioxide (CO2) gas is widely used for luminal insufflation during endoscopic retrograde cholangiopancreatography (ERCP) of the biliary tract. While frequently observed during routine...
An enzyme with high affinity for carbon dioxide. It catalyzes irreversibly the formation of oxaloacetate from phosphoenolpyruvate and carbon dioxide. This fixation of carbon dioxide in several bacteria and some plants is the first step in the biosynthesis of glucose. EC 220.127.116.11.
Any chemical species which accepts an electron-pair from a LEWIS BASE in a chemical bonding reaction.
Any chemical species which acts as an electron-pair donor in a chemical bonding reaction with a LEWIS ACID.
A family of zinc-containing enzymes that catalyze the reversible hydration of carbon dioxide. They play an important role in the transport of CARBON DIOXIDE from the tissues to the LUNG. EC 18.104.22.168.
The collective name for the boron hydrides, which are analogous to the alkanes and silanes. Numerous boranes are known. Some have high calorific values and are used in high-energy fuels. (From Grant & Hackh's Chemical Dictionary, 5th ed)
