amideshydrido complexeslithiumsodiumCyclic and bicyclic intermediates such as the THF-adduct 1 can be isolated from the reaction of a primary amine with LiAlH4. It is assumed that these compounds are generally formed in the reduction of organic nitrogen-containing compounds with LiAlH4. The ...
The Suzuki reaction also exhibits good functional group compatibility due to the relatively poor nucleophilicity of boronic acids and tolerates substrates containing aldehydes, amides, cyanides, esters, ethers, and nitro groups. Mechanistically, the Suzuki coupling reaction begins with the oxidative ...
O 1. LiAlH4 in ether CH3CH2CH 2. H2O CH3CH2CH2OH The first step toward understanding the difference between these reactions involves noting that the first reaction uses a nonpolar reagent to reduce a nonpolar double bond. The atoms on the surface of a metal are different from those buried ...

Therefore, alkali metalamides can be applied in a number of chemical synthesis aseff i cient deprotonating agents [3]. In ionic metal hydrides,elements possessing positive charges are metals, while H isnegatively charged [4]. The lone pair of N in amide mayexecute Coulombic potential onto ...
The Bischler–Napieralski reaction, which is used to prepare dihydroisoquinolines from phenylethylamides, isndemonstrated by the reaction of (S)-1-alkyl-1,2-diphenylethylamides with POCl3–P2O5. The reaction generated 3-nalkyl-4-phenyl-1,2-dihydroisoquinolines with stereochemical selectivities of ...
