Catalytic C–C Bond Formation Promoted by Organo- and Amidomagnesium(II) Compounds

Mg­(mesC­{NCy}2)­(N­{SiMe3}2)­(THF)
is a (pre)­catalyst for C–C bond formation. Attempted isolation
of intermediates in a proposed catalytic cycle was hindered by facile
ligand redistribution. A subsequent investigation of commercially
available organo- or amidomagnesium­(II) compounds (including Grignard
reagents) demonstrated similar catalytic behavior.

Mg(mesC{NCy}2)(N{SiMe3}2)(四氢呋喃(THF))是一种用于碳-碳(C-C)键形成的（预）催化剂。在尝试分离所提出的催化循环中的中间体时，因配体重分布反应易于发生而受阻。后续对市售有机镁(II)或酰胺镁(II)化合物（包括格氏试剂(Grignard reagents)）开展的研究表明，其展现出相似的催化行为。
