catalytic reaction
61Mannich reaction — The Mannich reaction is an organic reaction which consists of an amino alkylation of an acidic proton placed next to a carbonyl functional group with formaldehyde and ammonia or any primary or secondary amine. The final product is a β amino… …
62Pictet-Spengler reaction — The Pictet Spengler reaction is a chemical reaction in which a beta; arylethylamine such as tryptamine undergoes ringclosure after condensation with an aldehyde. Usually an acidic catalyst is employed and the reaction mixture heated, [] An… …
63Coupling reaction — A coupling reaction in organic chemistry is a catch all term for a variety of reactions where two hydrocarbon fragments are coupled with the aid of a metal catalyst. In one important reaction type a main group organometallic compound of the type… …
64Mitsunobu reaction — The Mitsunobu reaction is an organic reaction that converts an alcohol into a variety of functional groups, such as an ester, using triphenylphosphine and an azodicarboxylate such as diethyl azodicarboxylate (DEAD) or diisopropyl azodicarboxylate …
65Aza-Baylis-Hillman reaction — The Aza Baylis Hillman reaction or aza BH reaction in organic chemistry is a variation of the Baylis Hillman reaction and describes the reaction of an electron deficient alkene usually an α,β unsaturated carbonyl compound with an imine in the… …
66Kulinkovich reaction — The Kulinkovich reaction describes the organic synthesis of cyclopropanols via reaction of esters with dialkyldialkoxytitanium reagents, generated in situ from Grignard reagents bearing hydrogen in beta position and titanium(IV) alkoxides such as …
67Nozaki–Hiyama–Kishi reaction — The Nozaki Hiyama Kishi reaction is a nickel/chromium coupling reaction forming an alcohol from the reaction of an aldehyde with a allyl or vinyl halide.[1] In their original 1977 publication, Tamejiro Hiyama and Hitosi Nozaki [2] reported on a… …
68Pinacol coupling reaction — A pinacol coupling reaction is an organic reaction in which a carbon carbon covalent bond is formed between the carbonyl groups of an aldehyde or a ketone in presence of an electron donor in a free radical process Ref|1. The reaction product is a …
69Dowd–Beckwith ring expansion reaction — The Dowd–Beckwith ring expansion reaction is an organic reaction in which a cyclic β keto ester is expanded by up to 4 carbons in a free radical ring expansion reaction through an α alkylhalo substituent [1] [2] …
70Doyle-Kirmse reaction — The Doyle Kirmse reaction is an organic reaction in which in the original scope an allyl sulfide reacts with trimethylsilyldiazomethane to form the homoallyl sulfide compound.[1] The reaction was first reported by W. Kirmse in 1968 [2] and… …
