Synthesis and crystal structure of ( E )‐[(2‐cyclohexenyl)vinyl]triaryitin

( E )‐[(2‐Cyclohexenyl)vinyl]triaryitin (aryl=phenyl, p ‐tolyl) were synthesized and characterized by elemental analysis, IR, 1 H NMR spectroscopy. The crystal structure of ( E‐ )[(2 cyclohexenyl)vinyl]triphenyltin was also determined by the X‐ray diffraction. Experiments show that this compound has the conjugated system, which makes it have possible bioactivity and antitumor activity.
