Calcium May 23, 2013 Finally, alkylamide-imide precursors were investigated for the ALD of Nb2O5 and Ta2O5 thin films.

Together they form a unique fingerprint.

Alkali metal silylamides are soluble in a range of organic solvents, where they exist as aggregates, and are commonly used in organic chemistry as strong sterically hindered bases. They are also extensively used as precursors for the synthesis other bis(trimethylsilyl)amide complexes (see below). Group 2 complexes[edit]

Water was used as an oxygen source during these experiments. As deposited, these films exhibited a smooth surface with a measured roughness equivalent to that of the This study described an efficient and practical approach for amide synthesis. The reaction was conducted under metal- and solvent-free conditions at a mild temperature (40 °C) in air, and readily precursors.

Written by internationally recognised leaders in the field, Metal Amide Chemistry is the authoritative survey of this important class of compounds, the first since Lappert and Power’s 1980 book “Metal and Metalloid Amides.” An introduction to the topic is followed by in-depth discussions of the amide compounds of: Ammosamides E-F (1-2), are amidine analogs of the ammosamide family of alkaloids isolated from a marine-derived Streptomyces variabilis. Further studies with S. variabilis revealed a variety of aryl and alkyl amines added into the fermentation media could be efficiently incorporated into the ammosamide framework to generate a library of precursor-directed amidine analogs, ammosamides G-P (9 - 18). The Amine precursors, in contrast, are basic functional groups with average pK a values around 9.5, again depending on substitution adjacent to the amine. In contrast to these acidic or basic functional groups, the Amide product is considered a Neutral functionality.
