Medium-sized Cyclophanes. Part 76. 1 Synthesis of syn -9-methoxy (1,4)naphthaleno[3.3]metacyclophanes and their charge-transfer Complexes with Tetracyanoethylene in CH 2 Cl 2
The charge-transfer band of syn-9-methoxy(1,4)naphthaleno[3.3]metacyclophanes with tetracyanoethylene in CH2Cl2 are observed in the range of 604–606 nm, which is arising from the exclusive formation on the naphthalene ring due to the expanded π-electron density as well as the steric hindrance of the inner methoxy group at 9-position.
