Uses

Different sources of media describe the Uses of 1066-37-1 differently. You can refer to the following data:
1. Trimethylgermanium bromide is a reagent for the formation of dienolates of α,β-unsaturated esters.1 Also useful for methylenecyclopentane annulation reactions.
2. Reagent for the formation of dienolates of α,β-unsaturated esters. Also useful for methylenecyclopentane annulation reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 1066-37-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1066-37:
(6*1)+(5*0)+(4*6)+(3*6)+(2*3)+(1*7)=61
61 % 10 = 1
So 1066-37-1 is a valid CAS Registry Number.

Mechanism of the Reaction of (Arylthio)trimethylgermanes with 1-Aryl-1-bromoethanes--Kinetic and Stereochemical Studies--

Kozuka, Seizi,Nitta, Takemi,Tamura, Shoji,Tagaki, Waichiro

, p. 2594 - 2598 (1989)

Kinetic and stereochemical studies have been conducted on the reaction of (arylthio)trimethylgermanes with 1-aryl-1-bromoethanes.The reaction has been found to obey a first-order kinetic equation.The rates of the reaction of the substituted arylethanes were well-correlated with ?+ constants.Optically active 1-bromo-1-phenylethane gave racemic phenyl 1-phenylethyl sulfide by the reaction with trimethyl(phenylthio)germane.An SNL ionization of 1-aryl-1-bromoethanes has been suggested as the reaction mechanism.

Formation of Halide Complexes of Methyl- and Inorganic Germanium(IV) in Aqueous Hydrohalogenic Acid Solutions

Sohrin, Yoshiki

, p. 3363 - 3371 (2007/10/02)

The reaction of methyl- and inorganic germanium(IV) hydroxides ((CH3)nGe(OH)4-n; n = 1, 2, or 3) with halide ions (X = Cl-, Br-, or I-) to form halide complexes ((CH3)nGeX4-n) in aqueous acidic solution has been investigated by liquid-liquid extraction, solid-liquid distribution (ion exchange), and 1H NMR spectrometry.It has been found that methylgermanium moieties are hard Lewis acids similarly to inorganic germanium(IV), because the stability constant of the halide complexes decreases in the order Cl- > Br- > I-.The stability constant for an X- ion increases as the number of methyl groups attached to the germanium atom increases.The species of inorganic-, monomethyl-, and dimethylgermanium are nonionic and have a tetrahedral structure in HX solution, and OJ- ions attached to the germanium atom are stepwise substituted by X- ions with an increase in HX activity.Trimethylgermanium alone forms a cation, when the activity of HX is not sufficiently high.These facts suggest that the transfer of a negative charge from methyl groups to the central germanium atom lowers the stability of the bond between the germanium atom (hard acid) and an OH- ion (hard base).
