Grignard Reagent Formation - From the Lab to Industry (English)
In-situ production of Grignard reagents with continuous process control:
Since its discovery more than 100 years ago, the synthesis of Grignard reagents and their conversion with a variety of organic molecules such as ketones and aldehydes has been one of the most effective methods of C-C bond formation. In the synthesis of the top 50 active pharmaceutical ingredients, in about 10 percent of the synthetic pathways one Grignard reaction or more can be found.

Wicked!
What about cases where the Grignard reagent is not readily formed? For example, substitued halobenzenes may react slower than unsubstitued ones (e.g. bromobenzene vs 5-bromo-1,3-benzodioxole).
