Definitive Heat of Formation of Methylenimine, Ch 2 =nh, and of Methylenimmonium Ion, Ch 2 Nh
A long-standing controversy concerning the heat of formation of methylenimine has been addressed by means of the W2 (Weizmann-2) thermochemical approach. Our best calculated values, ∆H◦ f,298(CH2NH)=21.1±0.5 kcal/mol and ∆H◦ f,298(CH2NH + 2 )=179.4±0.5 kcal/mol, are in good agreement with the most recent measurements but carry a much smaller uncertainty. As a byproduct, we obtain the first-ever...
متن کاملA STUDY OF THE SILYLATION REACTION OF IMINES WITH TRIMETHYLCHLOROSILANE IN THE PRESENCE OF LITHIUM
A mixture oftrimethylchlorosilane (TMS-Cl), lithium and tetrahydrofuran (THF) reacts with imines to produce disilyl compound by addition of two trimethylsilyl (TMS) groups to the double bond of the imine. On hydrolysis the TMS on nitrogen is substituted by hydrogen and yields ? -silylamine. In the presence of acetyl chloride (CH COC1), benzene and pyridine, the ?-silyamine produces the corresp...
متن کاملCrystal structure of AI ( tBu ) 3 ( NH 2 CH 2 CH 2 Ph ) : A molecular " slinky "
The molecular structure of AI(tBu)3(NH2CH2CHzPh) is determined by the crystal packing of the phenyl rings and the pseudo spherical Al(tBu)3 units, and may be viewed as a layered structure consisting of double sheets of the phenyl rings and the Al(tBu)3 units. The A1-N-C-C linkage shows severe disorder as a result of its flexibility. The structure of Al(tBu)3 (NH2CH2CH2Ph) can be likened to a mo...
متن کاملChiral molecule formation in interstellar ice analogs: alpha-aminoethanol NH 2 CH(CH 3 )OH
Aims. Aminoalcohol molecules such as alpha-aminoethanol NH2CH(CH3)OH may be aminoacid precursors. We attempt to characterize and detect this kind of molecules which is important to establish a possible link between interstellar molecules and life as we know it on Earth. Methods. We use Fourier transform infrared (FTIR) spectroscopy and mass spectrometry to study the formation of alphaaminoethan...
