Metal carbene olefin metathesis catalysts

A metal carbene olefin metathesis catalyst represented by the structure of Formula (V):

• wherein
• Q is a two-atom linkage having the structure —CR11R12—CR13R14— or —CR11═CR13—, wherein R11, R12, R13, and R14 are independently hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, or functional groups;
• R3 and R4 is unsubstituted phenyl or phenyl substituted with one or more substituents selected from the group consisting of C1-C20 alkyl, substituted C1-C20 alkyl, C1-C20 heteroalkyl, substituted C1-C20 heteroalkyl, C5-C24 aryl, substituted C5-C24 aryl, C5-C24 heteroaryl, C6-C24 aralkyl, C6-C24 alkaryl, or halide;
• X1 and X2 are independently halogen;
• and are bonded to Ru in a trans orientation;
• L2 is represented by Formula (1) or Formula (2):
• wherein:
• R1p, R2p, R3p are each independently substituted or unsubstituted C6-C10 aryl, or substituted or unsubstituted C1-C10 alkyl, or substituted or unsubstituted C3-C8 cycloalkyl,
• wherein:
• R8p, R9p, R10p are each independently substituted or unsubstituted C6-C10 aryl, or substituted or unsubstituted C1-C10 alkyl, or substituted or unsubstituted C3-C8 cycloalkyl,
• m is 0, 1, or 2;
• R1 and R2 are independently hydrogen, hydrocarbyl, substituted hydrocarbyl, heteroatom-containing hydrocarbyl, substituted heteroatom-containing hydrocarbyl, or R1 and R2 may be linked together to form a ring that may be substituted or unsubstituted;
• and with the proviso that the catalyst of Formula (V) is not of structure:
