Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF9-BBN is more regioselective in the hydroboration of alkenes. Due to its rigid cyclic structure, it offers steric hindrance, thus attacking on terminal alkene rather than attacking on ring. Pd(PPh3)4 is widely used as a coupling agent.
Mechanism:
→In first step Pd(PPh3)4 will couple to the terminal alkene rather than the double bond present inside the ring.
→In second step it couples ph to terminal carbon leaving Br-BBN.
Conclusion:
So, the correct option is option A.
