As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. Formula: C17H14O, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 538-58-9
Preparation of N,N-bis(trimethylsilyl)-1-alkenesulfenamides and their desilylative conversion to 1-alkenesulfenimines. New stable 1-alkenesulfenic acid derivatives
Eight stable N,N-bis(trimethylsilyl)-1-alkenesulfenamides (3) were synthesized by the reaction of 1-alkenesulfenate anions with TMSCI and LiHMDS. Compounds 3 were isolated either by distillation or by chromatography. 1-Alkenesulfenamides (3) can be desilylated in the presence of aldehydes and ketones that do not bear alpha- hydrogens, to afford 1-alkenesulfenimines (7) either as single isomers or as mixtures of geometric isomers about the C=N bond. Protodesilylation of compounds 3 leads to 1-alkenesulfenamides (8) that have only hydrogens on the nitrogen. The parent 1- alkenesulfenamides 8 are not particularly stable, but could be characterized.
