Work

In 1887 discovered the Reformatsky reaction, during which a zinc
Zinc
Zinc , or spelter , is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2...

 organic compound is the key component.
The use of zinc in organic reactions was common at that time, but it was subsequently replaced by the more convenient magnesium. This was not possible for the reaction of α-chloro acids with ketone
Ketone
In organic chemistry, a ketone is an organic compound with the structure RCR', where R and R' can be a variety of atoms and groups of atoms. It features a carbonyl group bonded to two other carbon atoms. Many ketones are known and many are of great importance in industry and in biology...

s, because the magnesium based Grignard reagents are more reactive and lead to other products. This made the Reformatsky reaction a convenient way for the synthesis of β-hydroxy acids which were difficult to obtain with other methods.
