The third effect of electrodes of a polarizing current applied on a nerve denotes, as described by Suzuki (1) and Suzuki, Ando and Miyata (2), the effect of a longer or stronger polarization, which causes changes in the threshold of stimulation under both electrodes in direction opposite to those due to the electrotonus. The changes in the threshold by the electrotonus, which appear soon after ...
The regiocontrolled preparation of triarylisothiazoles is presented. 3-Halo-5-phenylisothiazole-4-carbonitriles, 1 (hal=Cl) and 18 (hal=I), are converted into the corresponding 4-bromo derivatives 5 (3-hal=Cl) and 24 (3-hal=I) via a Hunsdiecker strategy while the 4-iodo analogues 7 (3-hal=Cl) and 22 (3-hal=I) are prepared via a Hoffmann and Sandmeyer strategy. Regioselective Suzuki, Stille and ...
Sarvepalli and Klappenecker showed how to use classical one-point codes on the Hermitian curve to construct symmetric quantum codes. For the said curve, Homma and Kim determined the parameters of a larger family of codes, the two-point codes. For the Suzuki curve, the bound due to Duursma and Kirov gave the exact minimum distance of Suzuki two-point codes over F8 and F32. Of more recent develop...
Abstract Suzuki–Miyaura coupling is an extremely useful way to construct Csp2–Csp2 carbon bonds. On the other hand, Csp2–Csp3 reactions do not work well, and tert-alkylative particularly challenging due problematic oxidative addition β-hydride elimination side reactions. In this short review, we will introduce recent examples of couplings with tert-alkyl electrophiles or -boron reagents. The re...
