The hydride complexes [RuH{κ 3 ( N , N , N )‐Tp}(PPh 3 )(pta)] ( 1 ) and [RuH{κ 3 ( N , N , N )‐Tpms}(pta) 2 ] ( 3 ) [Tp = hydridotris(pyrazol‐1‐yl)borate, Tpms = tris(pyrazol‐1‐yl)methanesulfonate, pta = 1,3,5‐triaza‐7‐phosphatricyclo[3.3.1.1 3,7 ]decane] reacted with alkynes to form the corresponding neutral alkenyl complexes through insertion reactions. The addition of HBF 4 to the hydride complex [RuH{κ 3 ( N , N , N )‐Tp}(PPh 3 )(pta)] ( 1 ) led to a coordinatively unsaturated complex through the loss of hydrogen. The free coordination site can be occupied by different groups, such as BF 4 or NCMe.
