A base generated by the electroreduction of 2-pyrrolidone deprotonated trifluoromethane to form a trifluoromethyl anion equivalent.In the presence of hexamethyldisilazane, this species reacted with a variety of aldehydes and ketones to afford (trifluoromethyl)-carbinols in high yield.

, (2008/06/13)
A monomer containing an electron-withdrawing group of the present invention is represented by following Formula (a), (b) or (c): wherein A1, A2, and A3 are each a ring; Ra, Rb, Rc, and Ru are the same or different and are each a hydrogen atom or organic group; at least one of Rs, Rw and Rv, at least one of Rt and Rw1, and at least one of the two Rw2s are each an electron-withdrawing group, and the others are each a hydrogen atom or organic group; W1 is a single bond or linkage group; and n denotes an integer of 2 to 25, where at least two of Ra, Rb, Rc, Rs, Rt, Ru, Rv, Rw, Rw1, Rw2, W1, and carbon atoms constituting ring A1, carbon atoms constituting ring A2, and carbon atoms constituting ring A3 may be combined to form a ring, respectively. The electron-withdrawing groups in Rs, Rt, Rv, Rw, Rw1, and Rw2 are, for example, groups each containing a fluorine atom. The monomer is useful as a raw material for photoresist polymeric compounds.
