Abstract

To investigate the nature of nonbonded Se⊙⊙⊙ O interactions, three series of 2- substituted benzeneselenenyl derivatives [2-(CHO) C6H4SeX (1), 2-(CH2OH) C6H4SeX,(2), 2-(CH2O i Pr) C6H4SeX (3); X= Cl, Br, CN, SPh, SeAr, Me] were synthesized. The 17O NMR absorption observed for 17O-enriched aldehydes 1 appeared upfield relative to benzaldehyde (PhCHO), while the opposite downfield shifts relative to benzyl alcohol ( ...
