✦ Synopsis

Micro-Raman and infrared spectra were recorded at room temperature for several silylated N-benzoylcytidine, -adenosine and -guanosine derivatives. The distinctions between 2º-and 3º-silylated N-benzoylribonucleosides isomers can be observed from Raman spectra (500-700 and 1050-1350 cm-1 for silylated N-benzoylcytidine ; 550-700 and 1100-1400 cm-1 for silylated N-benzoyladenosine ; 500-700 and 1100-1700 cm-1 for silylated Nbezoylguanosine) and infrared spectra (1000-1200 cm-1 for all three kinds of 2º-and 3º-isomers). Based on these and other vibrational spectroscopic data, 2º-and 3º-silylated N-benzoylribonucleoside isomers can be readily distinguished from one another. Such distinctions should be useful in future directed syntheses of long-chain DNA and RNA fragments.

Raman and infrared spectra were recorded for crystalline adenosine samples at 300, 150 and 20 K. Data were taken over the entire spectral range from 20 to 3600 cm -1 . The wavenumbers of most vibrational modes were found to increase with decrease in temperature, but those near 3000 cm -1 showed the

Twelve para-and meta-substituted benzhydroxamic acids were subjected to exhaustive silylation with N-(tert-butyldimethylsilyl)-N-methyltrifluoroacetamide (with 1% of tert-butyldimethylsilyl chloride as a catalyst). In all cases only one product was isolated. According to the assigned NMR spectra ( 1
