Multiply Bonded Germanium Species

摘要: Publisher Summary The fact that intermediates with silicon doubly bonded to carbon, oxygen, sulfur, nitrogen, or have been described and fully characterized for several years, no such germanium intermediate was until 1973. Intermediates phosphorus, are, like their silaanalogs, very unstable. germanones thus generated were identified by various trapping reactions methoxygermanes, oxagermacyclopentane, ethylene oxide. reactivity of azide increases the electrophilic character germylenes. This is consistent a nucleophilic attack on germylene leading bipolar intermediate, which decomposes generating nitrogen forming germaimine. Germaphosphimine silaphosphimine species dicoordinated phosphorus can be obtained from 2-germa 2- silaphosphetanes thermal β-decomposition reaction. In study GeH 2 , Kraus claimed it likely dihydride dimer atoms upon addition sodium one bond broken form salt NaH GeGeH Na. first theoretical studies carried out Gowenlock Hunter. instability makes spectroscopic observation measurement difficult. Doubly species, as well germylenes, are great fundamental practical interest. These powerful synthetic reagents in organometallic chemistry.
