Acetylides aluminium

Interaction with aluminium carbide is incandescent, and with caesium acetylide at 350°C is explosive. Other related compounds may be expected to be oxidised violently if unmoderated.

Saturated non-acetal dimers, such as 153 and 154, can be prepared from 151 via aluminium acetylide condensations or Friedel-Crafts reactions. Although the acetylenic dimer 153 is /3-linked to C-10 of the artemisinin skeleton, the aryl dimer 154 is a-linked <1999JME4275>.

Acetylenic and Allenic Prostaglandins.— The Searle group have outlined a synthetic route to the acetylenic PG analogues (178)—(181) involving conjugate addition of aluminium or gallium acetylides to the cyclopentenone (65) as a key step (Scheme 38). 

Alkenyl aluminium reagents can be also prepared by halogen/lithium exchange from the corresponding iodoalkene, followed by transmetalation with Et2AlCl. In this way, the formation of A1 acetylides is avoided and lower catalysts loading for the ECA are allowed (Scheme 10) [32, 44]. 

The Group 13 dichlorides of formula Ar MCb [AT = 8-(dimethylamino)-l-naphthyl M = Al, Ga or In) have been prepared by the salt elimination reaction of one equivalent of Ar Li with MCI3 in toluene solution at -78 °C. The X-ray crystal structures show that the aluminium and gallium compounds are monomeric while the indium compound is dimeric. Reduction of the aluminium monomer with LiAlH4 gives the dimeric dihydride [Ar AlH2]2. There has been a report of the first structurally characterised aluminium compounds with terminal acetylide groups (24, 25). ...
