Abstract
Two novel C-2-symmetric 1,1 ' -bis(oxazolinyl)metallocenes bearing two cata lytic sites each have been employed in the asymmetric phenyl transfer from organozincs to aldehydes. Both, ferrocene (3) and ruthenocene (10) give Ver y good yields and high enantioselectivities in the title reaction affording optically active diarylmethanols with up to 96% ee.
