  The present disclosure provides novel POZ-2 derivatives, methods for synthesizing POZ-2 derivatives and intermediates useful in such methods. In one embodiment, the POZ-2 derivative comprises two linear POZ chains of the present disclosure linked directly or indirectly to a branching moiety that contains a functional group for linking the POZ-2 derivative to the target molecule. Target molecule-POZ-2 conjugates are also described. In certain embodiment, the POZ-2 derivatives have low polydispersity values and a decreased amount of impurities produced by unwanted side reactions, such as, but not limited to, chain transfer.

  A titanium catalyst for reaction between a carbon-carbon unsaturated bond and a compound having an electrophilic functional group or an electrophilic reagent, said titanium catalyst being composed of a titanium compound represented by the formula (1) below         TiX1X2X3X4     (1) (where X1, X2, X3, and X4 denote independently a halogen atom, C1-20 alkoxyl group, aralkyloxy group, aryloxy group, or -NRxRy group (where Rx and Ry denote independently a C1-20 alkyl group or aralkyl group), and any two of X1, X2, X3, and X4 may form a ring.) and a Grignard reagent represented by the formula (2) below in a molar amount 1.5-2.5 times as much as the titanium compound.         R1MgX5     (2) (where R1 denotes a C2-10 alkyl group having a hydrogen atom at the β position and X5 denotes a halogen atom.) The titanium catalyst of the present invention activates the carbon-carbon unsaturated bond, which has a comparatively low reactivity, thereby catalyzing the reaction with an electrophilic functional group. It is inexpensive and industrially advantageous. When applied to reaction between a carbon-carbon unsaturated bond and an electrophilic functional group, it yields industrially a variety of adducts of a compound having a carbon-carbon unsaturated bond and a compound having an electrophilic functional group, and it also yields a variety of intramolecular adducts of a compound having a carbon-carbon unsaturated bond and an electrophilic functional group in the same molecule.

  一种钛催化剂，用于碳-碳不饱和键与具有亲电官能团或亲电试剂的化合物之间的反应，所述钛催化剂由下式（1）表示的钛化合物组成 TiX1X2X3X4 (1) (其中 X1、X2、X3 和 X4 独立地表示卤素原子、C1-20 烷氧基、芳氧基、芳烷氧基或 -NRxRy 基团（其中 Rx 和 Ry 独立地表示 C1-20 烷基或芳烷基），且 X1、X2、X3 和 X4 中的任意两个可形成一个环）和下式（2）表示的格氏试剂，其摩尔量为钛化合物的 1.5-2.5 倍。 R1MgX5 (2) (其中 R1 表示在 β 位有一个氢原子的 C2-10 烷基，X5 表示卤素原子)。 本发明的钛催化剂可激活反应活性相对较低的碳-碳不饱和键，从而催化亲电官能团反应。这种催化剂价格低廉，具有工业优势。当应用于碳-碳不饱和键与亲电官能团之间的反应时，它可在工业上生成具有碳-碳不饱和键的化合物与具有亲电官能团的化合物的各种加合物，还可在同一分子中生成具有碳-碳不饱和键的化合物与具有亲电官能团的化合物的各种分子内加合物。
