Abstract
A reinvestigation of the two known methods of preparation of the title compound 1 revealed that one of these leads to a mixture of 1 and 4‐[2‐(acetoxy)ethyl]‐1,2‐benzenediol (5). The other method yields only 2‐methoxy‐4‐(2‐phenylethyl)phenol (6). An unambiguous straightforward preparation of 1 by LiAlH~4~ reduction of 3,4‐dihydroxy‐1‐benzeneacetic acid (8) is described.

The title compound (C 10 H 10 O 2 Br 2 ) crystallizes in the orthorhombic space group P2 1 2 1 2 1 with a = 5.0319(2)Å, b = 13.5282(5)Å, c = 15.6289(6)Å, V = 1063.90(1)Å 3 , Z = 4, D x = 2.01 g/cm 3 at T = 293(2)K. The structure was solved by direct methods and refined by full-matrix least-squares p
The preparation and the crystal structure of the fl (brown) form of TiC13 have been re-examined. Accurate X-ray diffraction measurements on crystallographically pure samples, free from AI, allowed refinement of the structure originally proposed by the Natta school in 1958, and in particular to fix t
## Abstract Halogenation of 1,1,2,3,4,5‐hexaphenylstannole was reinvestigated. Reaction of the stannole with 2 equiv. of bromine gave 1‐bromo‐4‐dibromophenylstannyl‐1,2,3,4‐tetraphenyl‐1,3‐butadiene. Reaction of the stannole with iodine gave similar results. Reaction of the stannole with 1 equiv. o
