Okuda, Yasuhiro published the artcileIntramolecular cyclization mediated by silylmetalation of acetylenes with dimethylphenylsilylmethylmagnesium (PhMe₂SiMgMe)/cuprous iodide and radical nature of the reagent, Computed Properties of 81216-14-0, the publication is Tetrahedron Letters (1984), 25(23), 2483-6, database is CAplus.

HCC(CH₂)₃XR (X = bond, CH₂, CHMe, CHBu,CH₂CH₂; R = O₃SC₆H₄Me-4, O₃SMe, Br) underwent CuI-catalyzed reaction with Me₂SiPhMgMe to give 25-91% methylenylcycloalkanes I. However, the same treatment of HCCCH₂CHR¹O₃SMe (R¹ = H, Me) gave 30-45% methylenecyclopropanes II and 10-41% silylcyclobutenes III.
