A metal-free, visible light-induced [4+2] benzannulation of biaryldiazonium salts with alkynes was developed. With eosin Y as photoredox catalyst, a variety of 9-substituted or 9,10-disubstituted phenanthrenes were obtained via a cascade radical addition and cyclization sequence. Copyright
From Dichlorocyclopropanes to Furans and Cyclopentadienes via Vinylcarbenes

Base-induced elimination of dichlorocarbene adducts 2 to 9-alkoxyphenanthrenes 1 leads to furans 6, presumably via cyclopropenes 3 which undergo rearrangement to vinylcarbenes 4 and C-H insertion.By the same sequence, the 9-substituted alkylphenanthrene a
