atom-economic approaches to access different regioisomers. However, the regio-chemistry control to access all the possible results is still challenging especially for the reaction involving multiple addition steps. Herein, we reported regio-controllable cobalt-catalyzed sequentialhydrosilylation/hydroboration of arylacetylenes, delivering all the possible regio-outcomes with high regioselectivities (up to

acrolein and 2-methylcyclohexanone to produce the corresponding β-hydroxysilanes in good yield, but with only a 3–4% diastereomeric excess. Unfortunately, these diastereomers proved impossible to separate. Model studies employing the methyldiphenylsilyl group showed that these β-hydroxysilanes could be protiodesilylated to give the corresponding methyl alcohol. The products from the adduct with pivaldehyde
