The use of dad (and bian) ligands in the stabilization of main-group complexes, in particular metal–metal-bonded compounds, as well as the small molecule reactivity of these (low-valent) metal complexes, is summarized.

In this Account we describe a series of new reactions that we, and others, have reported that involve the transformation of C–F bonds into C–Mg, C–Al, C–Si, C–Fe and C–Zn bonds. We focus on the use of highly reactive main group nucleophiles and discuss aspects of reaction scope, selectivity and mechanism.1 Introduction1.1 The Fluorocarbon Industry and Sustainability1.2 Production of Fluorocarbons1.3 Properties of Fluorocarbons1.4 Our Work2 Results and Discussion2.1 Low-Valent Main Group Compounds2.1.1 Reactions with Fluoroarenes2.1.2 Reactions with Fluoroalkanes2.1.3 Reactions with Fluoroalkenes2.2 Main Group Nucleophiles (M1–M2)2.2.1 Reactions of M1–M2 Nucleophiles with Fluoroarenes2.2.2 Reactions of M1–M2 Nucleophiles with Fluoroalkanes2.2.3 Reactions of M1–M2 Nucleophiles with Fluoroalkenes3 Summary and Perspective

In this paper, we reported the smallest main-group dicarbide with all deltahedras, which is also the first main-group dicarbide with (n + 1) polyhedral skeletal electron pairs (PSEPs).

Various forms of asymmetry in the lengths of the bond between the central atom and sulphur, found in differing coordination environments of 1,1-dithiolate compounds involving main group atoms, have been successfully rationalized by considering both the valence shell electron pair repulsion theory and the effect of the restricted ligand bite distance.
