%X The preparation of some novel four-carbon electrophiles and electrophile intermediates is described. Thus, the chlorobutenyl  sulfone (5), the iodobutynyl  sulfone (6) and the hitherto unreported chlorobutynyl  sulfone (4) were prepared. The novel intermediates, containing a chelating imidazolyl functionality, the N- methylimidazolyl sulfides (13)-(15) were also prepared. However, they polmerized rapidly, thus preventing further synthetic manipulations. The preparation of the &#945;-( trimethylsilyl ) butadienyl sulfones (17) and (18) is described and the mode of formation of the intermediate &#945;- trimethylsilyl sulfides (21) and (22) from the trimethylsilylbutenyl sulfide (27) is discussed.
