Mechanism and kinetics of the homogeneous gas-phase thermal decomposition of methylgermane

Chemical route for Si/C coated germanium nanowires

“…The germylene is able to migrate on substrate surface and readily reacts with other germylene counterparts through dimerization [41,42]. .…”

Gas‐Phase Chemistry and Mass Spectrometry ofGe‐,Sn‐ andPb‐Containing Compounds

“…Thus, it is clear that decomposition of GeH 4 through its ground electronic state proceeds by initial formation of • •GeH 2 while decomposition from excited electronic states can proceed both by formation of • •GeH 2 and • GeH 3 . The homogeneous gas-phase thermal decomposition of methylgermane is considerably more complicated since several primary processes are possible in principle 203 . Three primary processes have been proposed based on the following considerations: (i) the activation energy of the reaction measured from the temperature dependence of the rate; (ii) the question of the source of methyl radicals in the overall mechanism; and (iii) measurements of the yields of HD and D 2 in the decomposition of CH 3 GeD 3 .…”

“…16 The parent 1,1-dimethylgermacyclobutane (37) has been synthesized and its thermal behavior studied. Gusel'nikov and coworkers first pointed out the gas phase pyrolysis of 1,1-dimethylgermacyclobutane differed significantly from its silicon analog (Scheme 13).…”

“…Methylgermane (3), for example was proposed to have two routes of decomposition apart from loss of H2 shown below, one of which is molecular elimination of methane, the other was the four-center elimination of H2 to give a germene. 16 The precursors were synthesized mainly through literature routes. The dihexylgermacyclopentenes 40 and 41 were made through the reaction of germanium diiodide (39) and the appropriate diene in a sealed vessel at 60 °C for 4 hours.…”
