The same expression holds for the transition state, except that the sum is over s - 1 oscillators and the frequencies are the vf. The Beyer-Swinehart algoritlnn [38] makes a very efficient direct count of the number...

Yields can be very good Beyer (402) reports a 90% yield when coupling 2-amino-4-phenylthiazole with the diazonium salt of aniline. The coupling of diazotized anilines under modified conditions has been reported in a work treating the preparation of antineoplastics (403). 

This set of compounds is the most thoroughly studied among derivatives of 2-aminothiazole, thanks to the Beyer group. Heterocychzation methods are most commonly used for their preparation (see Chapter II and Refs. 37, 341, and 513-520). Reaction of 2-diazothiazoles (277) with organometallics provides another synthetic method (Scheme 1711 (521). 2-Hydrazinothiazoles may also be obtained by the action of hydrazine on 2-bromothiazoles (388) or on 2-mercaptothiazoles (522). 

The benzidine-like rearrangement of 2-hydrazinothiazoles has been observed by the Beyer group (523, 546). This rearrangement may be very fast (539). but does not occur with 2.2 -hydrazothiazole (300). where the...
