Clive, Derrick L. J. published the artcileRadical cyclizations of geminal radical precursors, Recommanded Product: (4-Bromobut-1-yn-1-yl)trimethylsilane, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1991), 3263-70, database is CAplus.
Polycyclic structures, e.g., I (R = SiMe3, SiPh2Me), can be generated by double radical cyclization, using compounds, e.g., (RCCCH2CH2)2C(OH)CHCl2, having two groups, capable of being homolyzed, attached to a single carbon that is suitably located with respect to two unsaturated pendants.
