“…Alkenylsilanes are ideally obtained by hydrosilylation of alkynes because this is the simplest transformation from the point of view of atom economy. [6] Extensive research has been performed to obtain and functionalize the b-products (anti-Markovnikova ddition), which can be formed in high yield and selectivity with ppm amounts of Pt catalyst or with otherm etal catalystsi ncluding, among others, Ir, [7] Ru, [8] Rh, [8a, 9] and Co. [9e, 10] In contrast, a-vinylsilanes (Markovnikova ddition) are only accessibleb yafewm ethods so far, involving Ru, [3,11] Cu, [12] Rh, [13] and Co complexes [14] as catalysts in amounts of approximately 1mol %, and the development of methodologies to access them in as implea nd cheap way wouldo pen the door to the preparationo fn ew compounds and to simplify existing synthetic procedures for other molecules.
