Scalable anti-Markovnikov hydrobromination of aliphatic and aromatic olefins

To improve access to a key synthetic intermediate we targeted a direct hydrobromination-Negishi route. Unsurprisingly, the anti-Markovnikov addition of HBr to estragole in the presence of AIBN proved successful. However, even in the absence of an added initiator, anti-Markovnikov addition was observed. Re-examination of early reports revealed that selective Markovnikov addition, often simply termed "normal" addition, is not always observed with HBr unless air is excluded, leading to the rediscovery of a reproducible and scalable initiator-free protocol.

Direct and selective benzylic oxidation of alkylarenes via C-H abstraction using alkali metal bromides

A direct benzylic oxidation of alkylarenes via C-H bond abstraction was developed using alkali metal bromides and oxidants under mild conditions. This reaction proceeded with excellent selectivity by thermal oxidation or photooxidation to provide a broad range of carbonyl compounds containing electron-deficient aryl carbonyl compounds in high yields.

A practical synthesis of indanofan via one-pot bromination of 3- chloroethylbenzene

A practical synthesis of Indanofan (1), a potent herbicide discovered by Mitsubishi Chemical Co. Ltd., was achieved starting from commercially available 3-chloroethylbenzene (2). 3-Chloro-α-bromostyrene (3), which was converted to 1-chloro-2-(3-chlorophenyl)prop-2-ene (5) in 2 steps, was synthesized via one-pot bromination of 2. 2-Ethylindane-1,3-dione (6) was synthesized from ethyl butyrate and ethyl phthalate (11) using NaOEt. The coupling reaction of 5 with 6 followed by oxidation with AcOOH afforded 1 in a high overall yield.

3-substituted-α, β-dibromoethylbenzene and process for preparing the same

A novel 3-substituted α,β-dibromoethylbenzene of formula (I): STR1 wherein X represents a halogen atom or a trihalomethyl group, which is useful as an intermediate for pharmaceuticals or agricultural chemicals, is prepared by a simple and high yield proce

Process for the preparation of chloroarylacetylene precursors

Chloroarylacetylenes such as m-chlorophenylacetylene and certain precursors to such chloroarylacetylene are prepared by reacting a chloroarylbromide with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group on the carbon atom adjacent to the acetylene group in the presence of a dialkyl or trialkyl amine solvent and a catalyst system consisting of a palladium complex containing two halogen moieties and two tri-substituted phosphine moieties. Additional triphenylphosphine can be added. A cuprous iodide promoter is also employed in the reaction sequence.
