✦ Synopsis

High-vacuum thermolyses of the intramolecularly coor-quencies of these hydrides matches well the calculated harmonic frequencies at the MP2(fc)/6-311G+(2d, p) and dinated alanes Me 2 N(CH 2 ) 3 AlX 2 with X = Cl, Br (1, 2) were investigated with matrix isolation techniques. Among the B3LYP/6-311G+(2d, p) level of theory. Beside the monomeric HAlX 2 , the argon matrices of the thermolysis experiments products, which were identified with IR spectroscopy, ab initio calculations, and known literature data, are monomeric contained CH 4 , HCN, H 2 C=CH 2 , H 2 C=NMe, [H 2 CCHCH 2 ] • , H 2 C=CHCH 3 , and AlX n (n = 1-3; X = Cl or Br).
