1. A metal complex of formula II-c: wherein: M is molybdenum or tungsten; R8 is R1, or phenyl optionally substituted with one to five R9; each R9 is independently halogen or R1; R1 is an optionally substituted group selected from C1-20 aliphatic, C1-20 heteroaliphatic having 1-3 heteroatoms independently selected from nitrogen, oxygen, or sulfur, phenyl, a 3-7 membered saturated or partially unsaturated carbocyclic ring, an 8-10 membered bicyclic saturated, partially unsaturated or aryl ring, a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 4-7 membered saturated or partially unsaturated heterocyclic ring having 1-3 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 7-10 membered bicyclic saturated or partially unsaturated heterocyclic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaryl ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur; each of R2 and R3 is independently R′, —OR′, —SR′, —N(R′)2, —OC(O)R′, —SOR′, —SO2R′, —SO2N(R′)2, —C(O)N(R′)2, —NR′C(O)R′, or —NR′SO2R′, provided that R2 and R3 are not simultaneously hydrogen; each R7 is independently optionally substituted —Ar′; Ar′ is of the following formula: wherein:
t is 0-4;p is 0-6;each Ring B′ and Ring C′ is independently an optionally substituted group selected from phenyl, a 3-7 membered saturated or partially unsaturated carbocyclic ring, an 8-10 membered bicyclic saturated, partially unsaturated or aryl ring, a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 4-7 membered saturated or partially unsaturated heterocyclic ring having 1-3 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 7-10 membered bicyclic saturated or partially unsaturated heterocyclic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaryl ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur; andeach Rs is independently halogen, R′, —OR′, —SR′, —S(O)R′, —S(O)2R′, —OSi(R′)3, —N(R′)2, —NR′C(O)R′, —NR′C(O)OR′, —NR′C(O)N(R′)2, —NR′SO2R′, —NR′SO2N(R′)2, or —NR′OR′; each R′ is independently hydrogen or an optionally substituted group selected from C1-6 aliphatic, phenyl, a 3-7 membered saturated or partially unsaturated carbocyclic ring, an 8-10 membered bicyclic saturated, partially unsaturated or aryl ring, a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 4-7 membered saturated or partially unsaturated heterocyclic ring having 1-3 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 7-10 membered bicyclic saturated or partially unsaturated heterocyclic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaryl ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur, wherein:
two R′ groups on the same nitrogen atom are optionally taken together with the nitrogen atom to form an optionally substituted 3-8 membered, saturated, partially unsaturated, or aryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; wherein at least one Rs is —F, and the metal complex is other than |
