TL;DR: In this article , the authors focus on developments in well-defined molecular organometallic complexes of the group 12 metals across five key areas such as cyclopentadienyl and N-heterocyclic carbene complexes, metal hydrides, metal alkylperoxides (formed by oxygen insertion into metal alkls), and the low-oxidation state metal-metal bonded species.
Abstract: The chemistries of organozinc and organomercury reagents are quite well established over the years. Zinc in particular has become an integral part of modern synthetic organic chemistry. On the contrary, organocadmium chemistry has always been perceived as less interesting due to certain limitations. The organometallic coordination chemistries of these three metals, again especially of zinc, have advanced significantly over the last few decades, showcasing several unprecedented entities and novel reactivity including catalysis. This chapter focuses on developments in well-defined molecular organometallic complexes of the group 12 metals across five key areas such as cyclopentadienyl and N-heterocyclic carbene complexes, metal hydrides, metal alkylperoxides (formed by oxygen insertion into metal alkyls), and the low-oxidation state metal-metal bonded species.

TL;DR: In this paper, the stereochemistry of the reactions of symmetrical, α-mercurated L-menthyl phenylacetate and mercuribis-α,α′-camphor with mercuric bromide in acetone solution has been studied.
Abstract: 1.
The stereochemistry of the reactions of symmetrical, α-mercurated L-menthyl phenylacetate and mercuribis-α,α′-camphor with mercuric bromide in acetone solution has been studied. Both reactions are examples of electrophilic substitution at a saturated carbon atom.
2.
It is shown that the first reaction proceeds with retention of configuration at the carbon atom in question. The racemization observed at 56° is a secondary process.
3.
It is not possible to elucidate the stereochemistry of the reaction between mercuribis-αα′-camphor and mercuric acetate because the 3-bromomercuricamphor formed racemizes even in the cold by the action of mercuric acetate under the experimental conditions.
4.
By a study of the reaction of the symmetrical, α-mercurated L-menthyl ester with an equimolar quantity of hydrogen bromide the conclusion, drawn previously [1], that the symmetrization of organomercury salts proceeds with retention of the configuration at the saturated carbon atom was confirmed.

TL;DR: In this article, a new method was developed for the synthesis of organomercury compounds from complexes of acetaldehyde, acetone, cyclopentanone and camphor hydrazones.
Abstract: 1.
The oxidation of mercuric halide complexes of alicyclic and aliphatic hydrazones with yellow mercuric oxide leads to the formation of organomercury compounds whose structures depend on the oxidation medium.
2.
A new method was developed for the synthesis of organomercury compounds from complexes of acetaldehyde, acetone, cyclopentanone, cyclohexanone, and camphor hydrazones.
