The invention claimed is: 1. A method for preparing a poly(dicyclopentadiene) polymer, wherein the polymer is greater than 80% syndiotactic, comprising a step of: a) providing a compound of formula I: wherein: R 1 is —C(R 1a ) 3 ; each R 1a is independently an optionally substituted group selected from C 1-10 aliphatic, C 1-10 heteroalkyl 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 or polycyclic 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 3-7 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; or: two R 1a groups are optionally taken together with the carbon atom to which they are attached to form an optionally substituted 3-10 membered, monocyclic, bicyclic or polycyclic, saturated or partially unsaturated ring having 0-4 heteroatoms independently selected from nitrogen, oxygen or sulfur; or: three R 1a groups are optionally taken together with the carbon atom to which they are attached to form an optionally substituted 4-10 membered, bicyclic or polycyclic, saturated or partially unsaturated ring having 0-4 heteroatoms independently selected from nitrogen, oxygen or sulfur; each of R 2 and R 3 is independently —R, —OR, —SR, —N(R) 2 , —OC(O)R, —S(O)R, —SO 2 R, —SO 2 N(R) 2 , —C(O)N(R) 2 , —NRC(O)R, or —NRSO 2 R; or: R 2 and R 3 are optionally taken together with the carbon atom to which they are attached to form an optionally substituted 3-10 membered, monocyclic, bicyclic or polycyclic, saturated or partially unsaturated ring having 0-4 heteroatoms independently selected from nitrogen, oxygen or sulfur; each R is independently hydrogen or an optionally substituted group selected from C 1-10 aliphatic, C 1-10 heteroalkyl having 1-3 heteroatoms independently selected from nitrogen, oxygen or sulfur, phenyl, a 3-7 membered saturated or partially unsaturated carbocyclic ring, a 6-10 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 3-7 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;

R 4 is optionally substituted 5-14 membered heteroaryl having 1-4 heteroatoms independently selected from nitrogen, oxygen or sulfur, wherein at least one heteroatom is nitrogen; R 5 is —OAr a ; and Ar a is optionally substituted or a compound of formula II: wherein: each of R 2 and R 3 is independently —R, —OR, —SR, —N(R) 2 , —OC(O)R, —S(O)R, —SO 2 R, —SO 2 N(R) 2 , —C(O)N(R) 2 , —NRC(O)R, or —NRSO 2 R; or: R 2 and R 3 are optionally taken together with the carbon atom to which they are attached to form an optionally substituted 3-10 membered, monocyclic, bicyclic or polycyclic, saturated or partially unsaturated ring having 0-4 heteroatoms independently selected from nitrogen, oxygen or sulfur;
