Abstract:
A series of chalcogen analogues encompassing a ketone and chalcogenoketones [{PC(=E)P}Pd(PMe3 )] (E=O, S, Se, Te) was generated from a nucleophilic palladium carbene compound, [{PC(sp2 )P}Pd(PMe3 )] ([PC(sp3 )HP]=bis[2-(diisopropylphosphino)-phenyl]methyl, iPr2 P-C6 H4 -CH-C6 H4 -PiPr2 ). The thio-, seleno-, and telluroketone were all synthesized by means of an atom transfer from the respective chalcogens. The ketone analogue, however, required the use of nitrobenzene or nitrosobenzene as the oxygen-atom transfer agent.

Electrophilic Addition to Alkynes: Halogenation
Halogenation is another class of electrophilic addition reactions where a halogen molecule gets added across a π bond. In alkynes, the presence of two π bonds allows for the addition of two equivalents of halogens (bromine or chlorine). The addition of the first halogen molecule forms a trans-dihaloalkene as the major product and the cis isomer as the minor product. Subsequent addition of the second equivalent yields the tetrahalide.
