TLDR
In this paper, the infrared and Raman spectra have been measured for dimethylzinc and diethylzinc in various ethers, and for the same mixture with zinc chloride, bromide, and iodide in tetrahydrofuran.Abstract:
Infrared and Raman spectra have been measured for dimethylzinc and diethylzinc in various ethers, and for ethylzinc iodide in diethyl ether. Infrared spectra are also reported for mixtures of dimethylzinc and diethylzinc with zinc chloride, bromide, and iodide in tetrahydrofuran. It is concluded that for all the alkylzinc halide systems the Schlenk equilibrium lies predominantly on the side RZnX. The infrared spectra of a number of solid alkylzinc adducts have been measured, and the trends in the zinc–carbon stretching frequencies are briefly discussed.read more

Organozinc Compounds in Synthesis
TL;DR: In this article, the authors describe the development mainly after 1960 in synthetic reactions using organozinc compounds and present the reaction of the triplet carbene with olefins with cyclopropane derivatives in a nonstereospecific way and is accompanied by hydrogen abstraction.

TL;DR: In this paper, the speciation of tetrahydrofuran (THF) solution is examined and it is shown that the species in THF solution are, beyond a doubt, ZnMe2(THF)/ZnMeCl/ZnCl2.
