Synthesis of 9-Fluorenylidenes via Pd-Catalyzed C-H Vinylation with Vinyl Bromides

A facile and efficient approach for the synthesis of 9-fluorenylidenes has been developed via the palladium-catalyzed cross-coupling of 2-iodobiphenyls and vinyl bromides. The reaction involves the C-H activation of 2-iodobiphenyls and dual C-C bond formations. A range of 9-fluorenylidene derivatives, including diphenyldibenzofulvenes, can be synthesized with the reaction.

Isolation & Reaction of a New Arsonium Ylid: 2,7-Dichlorofluorenylidenetriphenylarsenane

A new stabilized arsonium ylid, 2,7-dichlorofluorenylidenetriphenylarsenane (2) has been reacted with a variety of substituted benzaldehydes to give 2,7-dichloro-9-arylidenefluorenes.Similarly, the ylid (2) also couples with furfural and cinnamaldehyde to give 2,7-dichloro-9-furfurylidenefluorene and 2,7-dichloro-9-cinnamylidenefluorene in good yields.Bis-fluorenylidene derivatives are obtained when 2 reacts with isophthalaldehyde or terephthalaldehyde.The products have been characterised by elemental analyses, IR and PMR data.
