5-Exo cyclizations of primary and secondary radicals with acylsilanes successfully give cyclopentyl silyl ethers. The corresponding 6-exo cyclizations are sensitive to changes of the size of silyl groups. Secondary radicals undergo 6-exo cyclizations with

Radical 1,5-exo cyclizations of acylsilanes involving secondary radicals are quite effective. In contrast 1,6-exo cyclizations are more sensitive toward steric effect. Tandem radical cyclization process can be designed.
