Mo(N-t-Bu)(Adene)(Me2Pyr)2(2a) (Adene = 2-Adamantylidene, Me2Pyr = 2,5-dimethylpyrrolide) and Mo(NAr)(Adene)(Me2Pyr)2(2b) (Ar = 2,6-diisopropylphenyl) were prepared through addition of LiMe2Pyr to Mo(N-t-Bu)(Adene)(Triflate)2(dme) and Mo(NAr)(Adene)(Triflate)2(dme) complexes, respectively. Addition of 1 equiv of [Me2PhNH][BArF4] (ArF= 3,5-(CF3)2C6H3) and more than 2 equiv of pivalonitrile to Mo(NC6F5)(Adene)(Me2Pyr)2, followed by 1 equiv of HMTOH (2,6-Mesityl2C6H3OH), led to isolation of yellow crystalline Mo(NC6F5)(Adene)(OHMT)(Piv)2(BArF4) (3, Piv = pivalonitrile). Reactions analogous to that for3were found to produce Mo(NC6F5)(Adene)[OC(CF3)3](Piv)2(BArF4) (4), Mo(NC6F5)(Adene)(OHMT)(PhF6CN)2(BArF4) (5; PhF6CN = 3,5-(CF3)2C6H3CN), Mo(NAr)(Adene)(OHMT)(PhF6CN)2(BArF4) (6), Mo(NAr)(Adene)[OC(CF3)3](Piv)2(BArF4) (7), and Mo(N-t-Bu)(Adene)(OHMT)(PhF6CN)2(BArF4) (8). Compounds3,6, and7were found to have basically square pyramidal structures withtransnitriles in two basal positions. The bisnitrile complexes are active metathesis catalysts in the presence of 1 equiv of B(C6F5)3, consistent with the 14e monononitrile cationic complexes being the active species. The 14e complex required for metathesis is accessed most readily in bis PhF6CN complexes.
