In 2022,Hartman, Tomas; Konecny, Jan; Mazanek, Vlastimil; Sturala, Jiri; Sofer, Zdenek published an article in Inorganic Chemistry. The title of the article was 《A Decade of Germananes: Four Approaches to Their Functionalization》.Name: Methyl 3-bromopropanoate The author mentioned the following in the article:
Since the 1st synthesis of germanane (GeH) reported in 2013, two-dimensional Ge-based materials were intensively studied. Over the past decade, several methodologies for the functionalization of germanane were introduced. The 1st approach used exfoliation of Zintl phase CaGe2 with alkyl halides. Liu’s solvothermal method was used for the synthesis of Me germanane. Another methodol. used Ge-H activation with Na naphthalenide and its subsequent alkylation. All of these methods provide functionalized germananes; thus, a comparison of these methods is needed. Such a comparison of current synthetic approaches towards alkyl germananes is reported, and addnl., a new method for Ge-H activation using a NaK equimolar alloy is presented as a 4th approach. For this purpose, eight alkyl reagents were chosen representing reactive benzyl bromides as well as linear esters and nitriles because they contain easily trackable functional groups. The materials were characterized using FTIR spectroscopy, Raman spectroscopy, XPS, and TGA, and the data were compared. The comparison of all methods revealed not only some drawbacks for each method but also their advantages. The method using Na naphthalenide provided the lowest degree of surface coverage, whereas the solvothermal method seemed to provide materials with the highest degree of functionalization; unfortunately, the functionalization was also accompanied by a high degree of surface oxidation, i.e., (Ge-OH/Ge = O) formation. The highest degree of surface coverage accompanied by the lowest degree of surface oxidation was achieved employing Goldberger’s phase transfer direct exfoliation of CaGe2 as well as Ge-H activation using the NaK alloy with subsequent alkylation. The results came from multiple reactions, including the reaction of Methyl 3-bromopropanoate(cas: 3395-91-3Name: Methyl 3-bromopropanoate)
Methyl 3-bromopropanoate(cas: 3395-91-3) belongs to bromides. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact.Name: Methyl 3-bromopropanoate
