Favoured conformations of methyl isopropyl, ethyl isopropyl, methyl tert-butyl, and ethyl tert-butyl 2-(tri-phenylphosphoranylidene)malonate
(BLACKWELL PUBLISHING, 2008-07)
The conformations of organic compounds determined in the solid state are important because they can be compared with those in solution and/or from theoretical calculations. In this work, the crystal and molecular structures ...
Differences in the crystal structures of two dialkyl diester triphenyl-phosphonium ylids
(International Union of Crystallography, 2007)
Hydrogen bonding and crystal packing play major roles in determining the conformations of ethyl methyl 2-(triphenyl-phosphoranylidene)malonate, Ph3P=C(C02CH3)CO2CH2CH3 or C24H23O4P,(I), and dimethyl 2-(triphenylphosphora ...
