Reactive Intermediates in Carbon-Functional Organosilicon Reactions
Addition, substitution and reduction were observed to occur as competing processes in the reaction between vinyltrichlorosilane and isopropylmagnesium bromide, whereas only addition and reduction were observed in the reaction between vinyltrichlorosilane and tert-butylmagnesium chloride. …

The attempted synthesis of precursors of tetraaryldiazoethanes
This research involves the investigation of possible useful synthetic methods leading to tetraaryldiazoethanes of the type PhPh<sup>I</sup>Ph<sup>II</sup>CC(N<sub>2</sub>)PH<sup>III</sup> or their precursors. The synthesis of these compounds is of importance since the carbenoid and carbonium ion …

AN INVESTIGATION OF THE FEASIBILITY OF BIOMETHYLATION FOR GROUP IV METALS AND COMPOUNDS
… The process of environmental methylation of some toxic metals and metalloids has been briefly reviewed. Group IV metals (Sn, Pb) have found widespread industrial use in recent years. Use of lead and organolead chemicals has declined but tin and organotin chemicals production has been …

Mechanistic tracer studies of a synthetic mica-montmorillonite: n-butene isomerizations
… clay. The double bond isomerizations (including both double bond migration and rotation, but excluding structural rearrangements of the carbons) of the n-butenes were employed as the probe reactions. Product analyses were performed via gas chromatography and mass spectroscopy. The …

Studies on Solid-Phase Peptide Synthesis: The Synthesis of Glucagon
… group (Bpoc) for N<sup>α</sup>-amino protection; (2) the use of t-butyl based protecting groups for side chains of the trifunctional amino acids; and (3) the use of E-alkoxybenzyl-alcohol-resin as a solid support. At each step of the synthesis the N<sup>α</sup>-Bpoc moiety was removed by …

The oxymercuration of allenes
Addition of mercuric acetate to allene and the five possible methyl-substituted allenes was carried out in methanol. The reaction is quite rapid and even quantitative if an equivalent amount of sodium carbonate is added soon after initial mixing of the reagents. Allene yields exclusively …
