Abstract:	Treatment of a benzene or a CH₂Cl₂ solution of bis(N,N-dimethylcarbamoylseleno)methanes with SnCl₄ afforded β-1,3,5-triselenanes, and the key intermediates, acylselonium ions and selenoaldehydes, were successfully trapped by using allyltrimethylsilane or 2,3-dimethyl-1,3-butadiene to obtain the allylation products or the cycloadducts, respectively.

Keywords:	Bis(N N-dimethylcarbamoylseleno)methane Diselenoacetal Selenoaldehyde β-1 3 5-Triselenane Acylselonium ion
