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 α-( trimethylsilyl ) butadienyl sulfones (17) and (18) is described and the mode of formation of the intermediate α- trimethylsilyl sulfides (21) and (22) from the trimethylsilylbutenyl sulfide (27) is discussed.
A room temperature stable CuI-coordination polymer was characterized and pyrolysed to form a low density, thermoelectric composite with a relatively high Seebeck coefficient (∼1308 μV K−1) below 100 °C.
