The major changes now occurring worldwide are also affecting collective bargaining: the coverage of collective agreements is shrinking, and there are growing numbers of enterprise-based agreements and settlements concerning the public sector in many countries. Nevertheless, the adaptability of the international principles involved ensures their enduring validity. The authors describe the principles expressed in the ILO's Conventions and Recommendations and by the bodies charged with supervising compliance therewith. Finally, they give a general view of collective bargaining as a fundamental right and of the degree to which it is applied.
A detailed inspection of phenolic oxidation products derived from the o,o'-dihalogenated cresol derivatives (1a - 1e) indicated that the bromo and chloro substituents promoted the oxidation leading to the corresponding diaryl ethers, whereas the iodo derivatives provided the diaryls. Selective reduction of 6d and its tyrosine derivative afforded the corresponding diaryl ethers carrying two chlorine atoms (14, 15). interpretation of the selectivity of the phenolic oxidation was attempted by employing theoretical calculations.
