Blocking agents for organoborane compounds
An organoborane complex is disclosed. The complex includes a blocking agent comprising a bifunctional Lewis base. The blocking agents include an amine group and a second functional group that has a lower Lewis basicity than the first functional group. The blocking is based on amino alkyl pyridines.
1. An organoborane complex comprising:
an organoborane compound and a blocking agent, wherein the blocking agent corresponds to the formula
wherein n is 1-3, and R1-R4 are hydrogen or form a quinolin or isoquinolin-ring structure together with the pyridine ring.
2. The organoborane complex as set forth in claim 1 wherein n is 2.
3. The organoborane complex as set forth in claim 2 ,
wherein the organoborane compound corresponds to formula B-(R 2 ) 3 , wherein R 2 is a C 1-10 alkyl, C 3-10 cycloalkyl, or two or more R 2 are combined to form a cycloaliphatic ring structure.
