The remarkable crystal structure of the dimeric species [bis(ortho-anisyl)magnesium · THF]2
摘要:
The crystal structure of dimeric bis(ortho-methoxyphenyl)magnesium tetrahydrofuranate, 1, has been determined, and found to be remarkably unsymmetrical. The magnesium atoms in 1 have different coordination numbers and are connected by two ortho-methoxyphenyl groups each bridging in a unique fashion.

Go with the flow: A halogen–lithium exchange using BuLi or PhLi was performed in the presence of various metal salts (ZnCl2, MgCl2⋅LiCl) on a broad range of sensitive bromo- or iodo(hetero)arenes using a commercially available continuous-flow setup. The resulting diarylmagnesium or diarylzinc species were trapped with various electrophiles to give polyfunctional (hetero)arenes in high yields and with
