, p. 7345 - 7347 (2002)
A new and rapid approach to [5]helicenes is described. A central feature is the use of a sequential, non-reducing radical cyclisation reaction of (Z,Z)-1,4-bis(2-iodostyryl)benzene derivatives, viz. 3→1, mediated by tributyltin hydride.
Stabilized and persistent allenylketenes

, p. 2832 - 2838 (2007/10/03)
Photolyses of 2,3-bis(trimethylsilyl)-substituted methylenecyclobutenones 22-26 give essentially quantitative conversion to the allenylketenes 28-32 which have been isolated as long-lived species at room temperature. As predicted by molecular orbital calc
