A new synthesis of corannulene

Flash vacuum pyrolysis of 2-substituted benzo[c]phenanthrene has been exploited as a pivotal step in a new, simple synthesis of the 'bowl-shaped' hydrocarbon corannulene 1.

One-pot synthesis of gem-difluorostyrenes from benzyl bromide via olefination of phosphonium ylide with difluorocarbene

A new approach for the synthesis of gem-difluorostyrenes from benzyl bromide is described. Quaternization of triphenylphosphine with benzyl bromide to give phosphonium salts, deprotonation of the corresponding phosphonium salts to produce phosphonium ylide, and the subsequent olefination of phosphonium ylide with difluorocarbene generated from difluoromethylene phosphobetaine (Ph3P+CF2CO2-) by decarboxylation can occur smoothly in one-pot, furnishing the final gem-difluorostyrenes in good yields.

Synthesis and characterisation of [6]-azaosmahelicenes: The first d 4-heterometallahelicenes

[6]-Azaosmahelicenes, the first d4-heterometallahelicenes, have been synthesised and fully characterised. Their optical properties (UV-Vis absorption and luminescence) are reported.
