Treatment of bis(N,N-dimethylcar- bamoylseleno)methanes with SnCl4 afforded β-1,3,5-triselenanes in moderate to high yields, and the key intermediates of the reactions, i.e., 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. © 2006 Wiley Periodicals, Inc.
