Saint Blaise
Blaise of Sebaste ( hy, Սուրբ Վլասի, ''Surb Vlasi''; el, Ἅγιος Βλάσιος, ''Agios Vlasios''; ) was a physician and bishop of Sebastea in historical Armenia (modern Sivas, Turkey) who is venerated as a Christian saint and martyr. Blaise is venerated as a saint in the Catholic, Eastern Orthodox, and Oriental Orthodox churches and is the patron saint of wool combers and ENT illnesses. In the Latin Church, his feast falls on 3 February; in the Eastern Churches, on 11 February. According to the ''Acta Sanctorum'', he was martyred by being beaten, tortured with iron combs, and beheaded. Sources The first reference to Blaise is the medical writings of Aëtius Amidenus (c. AD 500) where his aid is invoked in treating objects stuck in the throat. Marco Polo reported the place where "Messer Saint Blaise obtained the glorious crown of martyrdom", Sebastea; the shrine near the citadel mount was mentioned by William of Rubruck in 1253. However, it appears to no l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blaise Reaction
The Blaise reaction is an organic reaction that forms a β-ketoester from the reaction of zinc metal with a α-bromoester and a nitrile. The reaction was first reported by Edmond Blaise (1872–1939) in 1901. The final intermediate is a metaloimine, which is then hydrolyzed to give the desired β-ketoester. Bulky aliphatic esters tend to give higher yields. Steven Hannick and Yoshito Kishi have developed an improved procedure. It has been noted that free hydroxyl groups can be tolerated in the course of this reaction, which is surprising for reactions of organometallic halides. Mechanism The mechanism of the Blaise reaction involves the formation of an organozinc complex with the bromine alpha to the ester carbonyl. This makes the alpha carbon nucleophilic, allowing it to attack the electrophilic carbon of the nitrile. The negative nitrile nitrogen resulting from this attack complexes with the zinc monobromide cation. The β-enamino ester (tautomer of the imine intermedia ...

Blaise Ketone Synthesis
The Blaise ketone synthesis (named after Edmond Blaise) is the chemical reaction of acid chlorides with organozinc compounds to give ketones. The reaction was claimed to bring excellent yields by Blaise, however, investigators failed to obtain better than moderate yields (50%). Thus, the reaction is particularly ineffective in forming ketones from acyl chlorides. The reaction also works with organocuprates. Reviews have been written. Reaction Mechanism The mechanism is sampled from the proposed mechanism for organocadmium compounds, given that the mechanisms are identical to one another the proposed mechanism for the reaction is the same as the one for organocadmium compounds. After the oxygen forms a bond with the organozinc compound, R’ shifts to the carbonyl carbon, having chlorine act as a leaving group and removing the negative charge from zinc. The chlorine that left returns to form a bond with zinc, pushing the electrons back on to oxygen and thus forming the keto ...
