Article abstract of DOI:10.1016/S0040-4039(01)90096-6

Reaction of 6-bromo-1-trimethylsilyl-1-hexyne with magnesium affords the corresponding Grignard reagent whose C-Mg bond intramolecularly adds to the trimethylsilylacetylene moiety in 5-Exo-Dig manner and suprafacially.The reaction can be applied to the synthesis of some cycloalkanes having stereodefined alkylidene substituents.
