The reactions of dithianes with W(CO) 6 in refluxing chlorobenzene give dimeric alkenes and their reduced products; fluorenone derivative yielding trimer 8. A radical mechanism is suggested. The structure of 8 has been determined by a single‐crystal X‐ray diffraction study. Crystal data: P2 1 /n; a = 11.948(5), b = 16.8795(14), c = 13.491(6) Å, β = 105.03(3)°, Z = 4, V = 2628(2) Å 3 ; R F = 0.061, R WF = 0.051 for 2142 reflections and 353 variables.
