Copper-catalyzed non-directed hydrosilylation of cyclopropenes: highly diastereoselective synthesis of fully substituted cyclopropylsilanes

The non-directed hydrosilylation of cyclopropenes with earth-abundant and environmentally benign base metal catalysis was described. This protocol is effective for a wide array of 3,3-disubstituted and 1,2-disubstituted cyclopropenes, and hence provides a facile and straightforward route to synthetically valuable polysubstituted and challenging fully substituted cyclopropylsilanes with high efficiency and diastereoselectivity.
