Facile Deprotection of Trimethylsilyl Ethers With Modified Borohydride Agents; 1-Benzyl-4-AZA-1-Azoniabicyclo[2.2.2]Octane Tetrahydroborate (Baaotb)1Versus Tetrabutylammonium Tetrahydroborate(TBATB)
摘要:
Deprotection of structurally different trimethylsilyl ethers with the modified borohydride agents BAAOTB and TBATB to their corresponding alcohols in reflexing t-BuOH is described. Both BAAOTB and TBATB are efficient reagents for this purpose. BAAOTB seems to be more selective than TBATB.
The authors explore consensus among economists on specific propositions on the basis of a fall 2000 survey of American Economic Association members. Because some propositions are drawn from earlier studies, the results illustrate the dynamics of opinion within the profession. The authors generally find consensus within the profession, although the degree of consensus varies between propositions that are international, macroeconomic, and microeconomic in nature. Consensus is particularly strong for propositions of free international trade and capital flows. In contrast, macroeconomic propositions exhibit a lower degree of consensus, partly because of increased agreement with monetarist and supply-side propositions over time. The profession displays substantial skepticism concerning claims of the "New Economy.".
