grignard reaction in a sentence
Examples
- It is used to manufacture pharmaceuticals and organic chemicals . 1-Bromohexane is also a solvent that is frequently used in grignard reactions, that are involved with creating bromo-cyclic compounds.
- The mechanism resembles the Grignard reaction, in which the metal alkoxide can be generated by a radical stepwise pathway, through single electron transfer, or concerted reaction pathway via a cyclic transition state.
- In his later years, Kharasch devoted his attention to studying the Grignard reaction and in 1954 co-authored a book with O . Reinmuth entitled " Grignard Reactions of Nonmetallic Substances ".
- In his later years, Kharasch devoted his attention to studying the Grignard reaction and in 1954 co-authored a book with O . Reinmuth entitled " Grignard Reactions of Nonmetallic Substances ".
- The Corriu group measured Grignard reaction half-times by NMR for related 18-crown-6 potassium salts of a variety of tetra-and pentacoordinated fluorosilanes in the presence of catalytic amounts of nucleophile.
- Organolithium compounds, especially " n "-butyllithium, are useful reagents in organic synthesis, as might be expected given lithium's diagonal relationship with magnesium, which plays an important role in the Grignard reaction.
- A Grignard reaction involving methylmagnesium bromide provided alcohol "'4 "', which was subjected to acid catalyzed Reduction and acylation gave diene "'7 "'( Scheme 3, compound 1 ).
- Samarium ( II ) iodide has become a popular reagent for carbon-carbon bond formation, for example in a Barbier reaction ( similar to the Grignard reaction ) between a ketone and an alkyl iodide to form a tertiary alcohol:
- In the history of the Nobel Prize in Chemistry awards have been given for the invention of specific organic reactions such as the Grignard reaction in 1912, the Diels-Alder reaction in 1950, the Wittig reaction in 1979 and olefin metathesis in 2005.
- Thus, while diethyl ether remains the solvent of choice for some reactions ( e . g ., Grignard reactions ), THF fills that role in many others, where strong coordination is desirable and the precise properties of ethereal solvents such as these ( alone and in mixtures and at various temperatures ) allows fine-tuning modern chemical reactions.
