Laser flash photolysis studies on alpha-methylbenzylchlorodiazirine, n-propylchlorodiazirine, and isopropylchlorodiazirine have been carried out at low temperatures, ranging from 170 to 230 K. The present results, together with those previously obtained with benzylchlorodiazirine and methylchlorodia...

Photolysis of alkylchlorodiazirines (1) in the presence of olefins gives a cyclopropane (3) by addition of the generated carbene to the olefin and a vinyl chloride derivative (2) resulting from a 1,2-H shift rearrangement. This rearrangement may occur either in the carbene or in some excited state, ...

Phenylchlorocarbene, generated by photolysis or thermolysis of the phenylchlorodiazirine, reacts with 2,2'-bipyridyl to give, in alkane solvents, the 6-phenyldipyrido[1,2-c:2',1'-e]i-midazolium chloride. We investigated the mechanism of the reaction by flash photolysis. Like the mechanism of formati...

Abstract: The photochemical reaction of M2@C80 (M = La and Ce) with 2-adamantane-2,3'-[3H]-diazirine (1) affords the corresponding adducts by carbene addition. The adducts were characterized by spectroscopic and single-crystal X-ray structure analyses. Crystallographic data for the adduct La2@C80(Ad...

The thermal decomposition of phenylehlorodiazirine (1), phenyl-n-butyldiazirine (2), and 2-adamantane-2,3'-[3H] diazirine (3) has been studied in solution in the presence Of C-60. The C-60 probe technique indicates that in the decomposition diazirine 1 yielded exclusively phenylchlorocarbene, diazir...

Irradiation of 2-adamantane-2,3'-[3H]-diazirine (1) in isooctane at room temperature gives two primary photoproducts, 2-diazoadamantane and 2-adamantylidene (Ad:), with quantum yields of about 0.5 each. The fluorescence quantum yield of 1 is small, phi(f) approximate to 10(-4). The reactivity of Ad:...

The article presents a research which discusses the preparation and characterization of the nanorods of the endohedral metallofullerene derivative lanthanum (La)@carbon(C)₈₂(Ad). The nanorods of La@C₈₂(Ad) were prepared by a liquid-liquid interfacial precipitation method. The s...
