Popis: The electrophilic Co(III) complex [Cp * (P(OMe) 3 )CoCH 2 CH 2 -μ-H] + BAr' 4 - (1; BAr' 4 - =B[3,5-(CF 3 ) 2 C 6 H 3 ] 4 - has been demonstratcd to be an efficient catalyst for the regiospecific hydrosilation of 1-hexene. The spectroscopic defection of the catalyst resting statc species [Cp * (P(OMe) 3 )CoCH(Bu)CH(SiEt 3 )-μ-H] + (2) in solutions of working catalyst systems has provided direct evidence for a silyl migration pathway
