Synthesis of Sterically Hindered 1,3-Connected Polyarylmethanes
摘要:
Sterically hindered 1,3-connected polyarylmethanes were prepared by repetitive additions of aryllithiums to carbonyl compounds. Synthetic routes with various degree of convergence were used. Variable temperature NMR spectroscopy, in conjunction with other techniques, was used to characterize the products.
