Coupling reactions of 1,1′-carbonyldiimidazole with Grignard reagents provide a rapid and straightforward method for the synthesis of symmetricalketones. Grignard reactions - coupling - acylations - 1,1′-carbonyldiimidazole - ketones
Tetraalkylmethanes are synthetic lubricants. The preferred structure contains four straight chain alkyl groups which may be the same or different and have from 1 to 2 or 5 to 14 carbon atoms. Mixtures are also disclosed as are novel methods for preparation of the tetraalkylmethanes.
