The reaction between Mo(C-t-Bu)(dme)Cl3 (dme = 1,2-dimethoxyethane) and Me3SiNHAr (Ar = 2,6-diisopropylphenyl) yields Mo(C-t-Bu)(NHAr)(dme)Cl2 (1), which upon treatment with a catalytic amount of NEt3 is transformed into Mo(CH-t-Bu)(NAr)(dme)Cl2 (2) virtually quantitatively. Complexes of the type Mo(CH-t-Bu)-(NAr)(OR)2 (OR = OCMe(CF3)2, OCMe2(CF3), or OCMe3) have been prepared. Mo(CH-t-Bu)(NAr)[OCMe(CF3)2]2 is an active metathesis catalyst (but less active than the tungsten analogue) while Mo(CH-t-Bu)(NAr)(OCMe3)2 does not react with ordinary olefins. Addition of Me3SiCH=CH2 to Mo(CH-t-Bu)(NAr)[OCMe(CF3)2]2 to yield Mo-(CHSiMe3)(NAr)[OCMe(CF3)2]2 is taken as evidence that molybdacyclobutane complexes lose an olefin more readily than analogous tungstacyclobutane complexes.
