Silane Nitrile: Matrix Isolation, Adduct with Hydrogen

Abstract

COMMUNICATIONS substrate selectivity of the catalyst A. A further pointer to the high selectivity of the catalyst was obtained with 7 and 8, whose transesterification was not measurably catalyzed by A within 12 h. Addition of 1 and n-hexanol to this mixture again yielded 2 immediately and selectively.

Theoretical study of the substituent effects on structure and dissociation of RNSi and RSiN (R = H, Li)

“…The equilibrium HSi and SiN bond lengths agree well with the reported values of Lind et al [15]. The vibrational frequency of SiN stretching mode (x 2 ) is about 10 cm -1 lower than the experimental value of Maier and Glatthaar [7] but it agrees very well with the theoretical value of Lind et al [15]. The HSi stretching mode (x 3 ) is about 30 cm -1 Table 1 Ground state energy (a.u.…”

“…The equilibrium HN and NSi bond lengths agree very well with the experimental values of Ogilvie and Cradok [1]. Both bending mode (x 1 ) and NSi stretching mode (x 2 ) agree well with the experimental values of Ogilvie and Cradok [1] and Maier and Glatthaar [7]. For NSi stretching mode (x 2 ), the CCSD(T) value agrees better with the experimental value of Elhanine et al [2] than the experimental value of Ogilvie and Cradok [1].…”

“…They determined the equilibrium rotational and vibrational parameters of HNSi with these four hot band frequencies for the first time. Maier and Glatthaar [7] reported a matrix isolation study of HSiN and its adduct. They observed the IR absorption for HSiN and HNSi and stated that the HSiN molecule is the first compound with a formal SiN triple bond of the nitrile type to be identified spectroscopically.…”

Stable Systems with a Triple Bond to Silicon or Its Homologues: Another Challenge

“…At this point the experimental evidence of formal triple bonds to silicon by matrix isolation spectroscopy (HSiN, [24] HNSi [25] and C 6 H 5 NSi [26] ), by neutralization reionization (NR) mass spectrometry (HCSiX (X F,Cl) [27] ), as well as by photoelectron spectroscopy (C 6 H 5 N Si [28] ) should be mentioned.…”

Structures, relative stability and dissociation of [Si,N,C,O]2+ isomers

“…The structures and stability of small molecules have received considerable attention in the fields of theoretical and experimental chemistry [1][2][3][4][5][6][7][8][9] , especially these molecules containing SiN and SiP multiple bonds [1,2] because of their important roles in material science and interstellar chemistry [9][10][11] . [Si,N,C,O] system is a typical organic-inorganic molecular system.…”
