A straightforward alkynylation of Li and Mg metalated heterocycles with sulfonylacetylenes.
Coupling of alkynyl moieties to heterocyclic rings, without using transition metals, can be easily performed by the reaction of aryl or heteroaryl sulfonylacetylenes with heteroaryl-Li compounds or their corresponding less reactive magnesium derivatives.
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولIRMPD spectroscopy of metalated flavins: structure and bonding of M(q+)-lumichrome complexes (M(q+) = Li⁺-Cs⁺, Ag⁺, Mg²⁺).
Infrared multiphoton dissociation (IRMPD) spectra of mass selected isolated metal-lumichrome ionic complexes, M(q+)LCn with M(q+) = Li(+), Na(+), K(+), Rb(+), Cs(+), Ag(+) (n = 1), and Mg(2+) (n = 2), are recorded in the fingerprint range. The complexes are generated in an electrospray ionization source coupled to an ion cyclotron mass spectrometer and the IR free electron laser FELIX. Vibratio...

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
CASTABILITY OF Al-Li-Mg AND Al-Li-Cu-Mg ALLOYS
The objective of the present work is to study the casting characteristics of various A1-Li alloys, which include fluidity and strengths of the alloys and their interaction with cast molds. Materials investigated are Al-Li-Mg and Al-Li-Cu-Mg alloys with Li content of 2.5 wt%. The results show that sand molds with resin binders are good for A1-Li casting. Ceramic coatings can further reduce the m...
