  initial formation of biarylmethanols via reaction of aryl Grignards with carbonyl compounds followed by a subsequent reduction with iodotrimethylsilane (TMSI). A number of improvements over existing literature procedures are reported as well as previously unobserved dimenzations. Studies reveal that as few as 3 equiv of TMSI will give complete reduction in most cases where either of the substituents are not
