Group I alkoxides are highly active precatalysts in the heterodehydrocoupling of silanes and amines to afford aminosilane products. The broadly soluble and commercially available KOtAmyl was utilized as the benchmark precatalyst for this transformation. Challenging substrates such as ...

The cationic nitrosyls, [IrCl3(NO)L2]+(L = PPh3, AsPh3) react with alcohols to give neutral iridium(III) complexes containing bound alkyl nitrites, IrCl3(RONO)L2(R = Me, Et, Pr). These reactions parallel the formation of complexes containing alkoxycarbonyl groups as ligands by alkoxide...
The compounds W,(OR), contain two important functionalities, the alkoxide group and the (W=W)'+ unit, and form versatile templates for organometallic chemistry. The reactions between W,(OR), compounds and alkynes give rise to a variety of products derived from either metathesis of the W=W ...
Group 5 (V, Nb, Ta) element-compounds have been used as catalysts for the trans-esterification of ethylene carbonate with methanol, ethanol or allyl alcohol to afford the relevant dialkyl carbonates. Vanadium species are the most active among the catalysts tested, with niobium showing a close re...
An alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They can be written as RO–, where R is the organic substituent. Alkoxides are strong bases and, when R is not bulky, good nucleophiles and good ligands....
-6a -methyl compound, dehydrating to the D 5-compound, refluxing with selenium dioxide to give the 4-hydroxy derivative, reducing the 11-keto group, removing the side chain protecting group and heating with an alkali metal alkoxide... FRIED JOHN,MROZIK HELMUT - US 被引量: 1发表: 1966年 ...
(OR)2], in which: MII means magnesium and/or calcium and/or strontium and/or barium; MIV titanium and/or zirconium and/or hafnium; R is an alkyl group with 1 to 18 carbon atoms; R1 is an alkyl group with 1 to 18 carbon atoms, y has a value of between 0 to 2; z has a ...
