Abstract: Hydroxylated benzophenonens are prepared from completely or partially methylated hydroxybenzophenones by reacting these methyl ethers with AlCl.sub.3 and subsequently hydrolyzing with water, the reaction being carried out in the presence of one or more compounds from the class of ureas or carboxamides.

Abstract: A nuclear magnetic resonance tomography apparatus has coils for respectively generating fundamental and gradient magnetic fields in which an examination subject is disposed, and RF coil for displacing the nuclear spins of the examination subject from an equilibrium position, and direct galvanic connections to the examination subject for obtaining the nuclear magnetic resonance signals arising during relaxation of the excited nuclear spins. The examination subject thus becomes a part of the reception antenna or the feed line thereof, thus avoiding the use of an RF coil for acquiring such signals.
