I he Reaction of Sulfur with Dilithio
نویسنده
چکیده
The sequential reaction of selected polycyclic aromatic hydrocarbons with butyllithium/TMEDA/ hexane and sulfur allows preparation of ring-fused dithiins, dithioles, and thiophenes. In this manner, phenanthrene has been converted to phenanthro[4,5-~de][1,2]dithiin and phenanthro[l,IOc~-1,2dithiole. Yellow crystals of the dithiin form inoC2/c (#15) space group .with < = 4, a = 13.537(3) A, b = 8.933(2) A, c = 9.601(4) A, and p = 116.19 (2)”; while orange crystals of the dithiob form in P2,2,2, (#19) space groyp with 2 = 4, a 4.1507(5) A, b = 14.436(3) A, and c := 16.972(3) A. Full structures have been determined for both compounds.

Synthesis, structure and reactivity of a 1-bromoalumole.
A stable 1-bromoalumole has been synthesized by the reaction of a 1,4-dilithio-1,3-butadiene derivative with AlBr3. The 1-bromoalumole was found to exist as a dimeric structure in the crystalline state. Reaction of the 1-bromoalumole with Mes*Li afforded the corresponding Mes*-substituted alumole (Mes* = 2,4,6-(t-Bu)3C6H2), demonstrating the potential of the 1-bromoalumole for the functionaliza...

In this study the effect of the alkylating agent, sulfur mustard, on calf thymus chromatin was investigated using UV/Vis spectroscopy, gel electrophoresis and thermal denaturation techniques. The results show that treatment of isolated chromatin with sulfur mustard releases histones from the core particles but does not affect histone H I and nonhistone chromosomal proteins. The content of ...
