TLDR
In this paper, it was shown that cycloocta-1,5-diphenylphosphinopentane is a stable product when the ligand is a monophosphine although ( o -methoxyphenyl)methylphenylphos- phine is an exception.About:

Mechanism of asymmetric hydrogenation catalyzed by a rhodium complex of (S,S)-1,2-bis(tert-butylmethylphosphino)ethane. Dihydride mechanism of asymmetric hydrogenation
TL;DR: The mechanism of asymmetric hydrogenation catalyzed by a new effective catalyst, viz., a rhodium complex of (S,S)-1,2-bis(tert-butylmethylphosphino)ethane (BisP*) has been studied by multinuclear NMR as mentioned in this paper.
