“…The configuration of all the palladium fragments in the molecules displayed Fig. 67 was trans; this could be ascertained by NMR spectroscopy and/or crystallography (101a-d), or by far-IR spectroscopy (102). With regard to the configuration of titanium, the homochiral isomer 102 (D,D or L,L) was the most stable one according to molecular modeling, as for 99a;[243] by contrast, 101b was a mesocate (D,L) according to its crystal structure, and molecular modeling confirmed its stability on the basis of steric considerations.…”
