During the past 100 years the Grignard reagents probably have been the most widely used organometallic reagents. Most of them are easily prepared in ethereal solution (usually diethyl ether or, since the early 1950s, THF) by the reaction of an organic halide with metallic magnesium (eq 1). (1) Most of them are stable in ethereal solution (although atmospheric moisture and oxygen should be.
The principal reaction of the alkynes is addition across the triple bond to form alkanes. These addition reactions are analogous to those of the alkenes.

The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the involvement of electronically excited states, generated upon absorption of photons. This produces transient reactive intermediates and.
Anion receptor chemistry concerns the design of molecules that recognize, respond, or sense species that carry a negative charge. This review covers advances in anion complexation in the years 2017 and 2018. The review focuses on the applications of anion receptor chemistry, including sensing, self-assembly, extraction, transport, catalysis, and fundamental advances in the area.
