Rock around the Ring: An Experimental and Theoretical Study of the Molecular Dynamics of Stannyltriphospholes with Chiral Tin Substituents

The reaction of diphenyltin dichloride with enantiopure Grignard reagents prepared in situ leads to diphenyltin chlorides 7a – e , which contain chiral organyl substituents. The 2‐bornyl derivative 7a forms a mixture of exo and endo isomers and the (–)‐menthyl derivative 7b yields a mixture of epimers, whereas the cis ‐ and trans ‐myrtanyl complexes 7c and 7d and the m ‐(2‐bornyl‐2‐ene)phenyl species 7e form only one enantiomer as the tin atom...
