BiPh3 has been used to synthesize alkaline-earth metal amides and alkaline-earth metal cyclopentadienides. The difference between HgPh2 and BiPh3 in these syntheses was that the reaction time was longer when using BiPh3.
BiPh3 is more effective in synthesizing alkaline-earth metal amides and cyclopentadienides than HgPh2, requiring a longer reaction time to complete the process.
