    Description: Great advances have been made in fundamental scientific research in recent years. The new knowledge gathered, in addition to deepening our understanding of the physical universe, contributes a range of abilities and opportunities to society that would not otherwise be available. Much research that may be called applied because it addresses needs of society is quite fundamental in character, and support of such research at the National Science Foundation is to be handled in tandem by the research directorates. Other areas that require a refocusing of support are engineering science and education, at all levels, in science and engineering. Increasing our strength in these areas is essential to achieve our national economic, social, and political goals. Steps are being taken by the National Science Foundation to make its structure better able to deal with engineering and applied research and to provide greater mutual reinforcement between applied and basic research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slaughter, J B -- New York, N.Y. -- Science. 1981 Mar 13;211(4487):1131-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7466384" target="_blank"〉PubMed〈/a〉

    Notes: Es wird die Synthese der 1.3.5-Triacetyl-2-desoxy-β-D-ribofuranose beschrieben. Die Struktur wird durch Messung der kernmagnetischen Resonanz unter Vergleich mit den beiden β-D-Ribose-tetraacetaten (1.3.4 bzw. 1.3.5) bewiesen.

    Notes: In Fortführung der Versuche über phosphinhaltige Kobaltcarbonyle hat sich ergeben, daß der Reaktionsverlauf von der speziellen Art des Phosphins, d. h. den am Phosphor gebundenen organischen Resten, abhängt. So entstehen mit Triäthyl- und Tricyclohexyl-phosphin bevorzugt (ca. 10°) die 2-ionigen Verbindungen [Co(CO)3L2][Co(CO)4] (L = P(C2H5)3, P(C6H11)3); nur bei höherer Temperatur (ca. 35°) und in indifferenten Mitteln bildet sich das betr. echte Derivat des Kobaltcarbonyls [Co(CO)3L]2, das mit Triphenylphosphin auch schon bei tieferer Temperatur entsteht. Häufig liegen Gemische beider Verbindungstypen vor.  -  Mit Triphenyl-arsin und -stibin sind die gleichfalls bei tieferer Temperatur (0°) gebildeten 2-ionigen Verbindungen nur labil und wandeln sich spontan unter CO-Abgabe in die echten Derivate um.  -  Ergänzende weitere Versuche wurden mit Mangancarbonyl und der 2-zähligen Base Äthylen-bis-[diphenylphosphin] und mit Rheniumcarbonyl und Triphenylphosphin durchgeführt. Im letzteren Fall erhält man das diamagnetische Monosubstitutionsprodukt [Re(CO)4P(C6H5)3]2.

    Notes: Eine Anzahl diazotierter heterocyclischer Amine wurde mit Phenoläthern und aromatischen Kohlenwasserstoffen auf ihr Kupplungsvermögen geprüft. Die Versuche zeigten, daß insbesondere Verbindungen aus der 1.2.4- und 1.3.4-Thiodiazol-Reihe eine sehr hohe Reaktivität besitzen, die diejenige des diazotierten 2.4-Dinitro-anilins deutlich übertrifft.
