The Ireland–Claisen rearrangement is a chemical reaction of an allylic ester with strong base to give an γ,δ-unsaturated carboxylic acid. [1] [2] [3]
The Ireland model In the Ireland model, the deprotonation is assumed to proceed by a six-membered or cyclic [ 19 ] monomeric transition state . The larger of the two substituents on the electrophile (in the case above, methyl is larger than proton) adopts an equatorial disposition in the favored transition state, leading to a preference for E ...
Robert E. Ireland (1929 – February 4, 2012) was an American chemist and the Thomas Jefferson Chair Professor of chemistry at the University of Virginia. He is known for his textbook Organic Synthesis [ 1 ] and his contributions to the Ireland–Claisen rearrangement chemical reaction.

After several years of inactivity, the Irish Chemical Association was formed on 14 March 1936. At the end of the 1940s, it became clear that the association needed to evolve to achieve greater government recognition. A series of meetings led to the formation of the present Institute of Chemistry of Ireland on 18 January 1950. [citation needed]
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds.These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation.

Coat of Arms of the RIC. The Royal Institute of Chemistry was a British scientific organisation. Founded in 1877 as the Institute of Chemistry of Great Britain and Ireland (ICGBI), its role was to focus on qualifications and the professional status of chemists, and its aim was to ensure that consulting and analytical chemists were properly trained and qualified.
He got a lectureship at University College Cork in 1937 and returned to Ireland in 1938. [4] Ó Ceallaigh remained at Cork until 1947, during which time he was conferred with the degree of Ph.D., [5] and then took a position at the University of Bristol working in a group assembled by the Nobel Prize winning particle physicist C F Powell.
