Synthesis and reactions of poly(ethynyldialkylsilanes)

Description: A nucleophilic cleavage reaction of 2,2,5,5,8,8-hexamethyl-2,5,8-trisilanona-3,6-diyne, I, with several bases, occurs rapidly at room temperature in both polar and non-polar solvents. An attack occurs exclusively at the central silicon regardless of the steric requirements of the bases (alkyllithium). The major products from the reaction of I with tert-butyllithium followed by hydrolysis were 2,2,5,5,6,6-hexamethyl-2,5-disilahepta-3-yne, II, and 2,2,5,5-tetramethyl-2,5-disilahexa-3-yne, VI.

Toxic chemical syndrome: body burden and immune parameters affected by environmental chemicals

Description: The purpose of the present study was to determine: (1) that dental office personnel would be exposed to more toxic chemicals in the workplace than the non-dental office controls; (2) that exposure should lead to a reduction in the efficiency of the immune system in the individuals in the dental office; and (3) the immunological deficit should manifest itself in psychological and/or physiological pathology as measured on the Profile of Mood States (POMS) and Bender Gestalt.
