NOVAL SYNTHESIS OF 1,3,5-TRISELENANES FROM ALDEHYDES, AND NOVEL GENERATION OF SELENOALDEHYDES BY FRAGMENTATION OF 1,3,5-TRISELENANES

10.1016/S0040-4039(01)93851-1

The study aimed to develop a new method for the synthesis of 1,3,5-triselenane from aldehydes and to generate selenoaldehyde via the fragmentation of 1,3,5-triselenane. The aim was to establish a convenient method for the generation of selenoaldehyde, a reactive intermediate containing a carbon-selenium double bond and of great importance in heteroatom chemistry. The researchers used chemicals such as (Me3Si)2Se (bis(trimethylsilyl)selenium) and Lewis acids such as BF3.OEt2 and SnCl4 in the reaction. The study concluded that 1,3,5-triselenane can be formed via the instantaneous generation of selenoaldehyde by treating aldehydes with (Me3Si)2Se in the presence of Lewis acids.
