“…In a first ionic reaction the title compound was treated with LiAlH 4 in ether at room temperature. To our surprise the two triple bond were reduced to double bonds within 1 h at room temperature and 1,2-benzo-1,3,7-cyclooctatriene (9) was obtained in 91 % yield (Scheme 4). The compound was identified by comparison of its spectroscopic data with those described in the literature.…”

The title compound 3,4‐benzocycloocten‐1,5‐diyne (1) is a highly reactive hydrocarbon that has been shown to undergo addition reactions with tetraphenyl‐cyclopentadienone(tetracyclone) to the 2:1 adduct 6, with octacarbonyldicobalt to the bis metal complex 7, with lithium aluminium hydride to the bis diene 9, and with various electrophilic reagents. In these latter cases cationic intermediates are generated from 1 and a transannular cyclization takes place leading to novel derivatives of 1,2‐dihydropentalene (31, 32, 35, 36, 43, 44).

“…The main limitation is that the detector has to be recovered after the flight for the analysis with microscopes. Such type of technique was already used succesfully in several experiments on balloons [4][5][6] and in space [7][8][9][10] Nuclear Track Detectors (NTDs) like CR39 R can detect charged particles with Z/β ≥ 5 with very good charge resolution [11], whereas Lexan R /Makrofol R polycarbonates have higher thresholds, Z/β ≥ 50 [12]. Due to the large flux of low charged particles the analysis of CR39 R detectors and the determination of the relative abundances can be time consuming.…”

CAKE (Cosmic Abundances below Knee Energies) was a prototype balloon experiment for the determination of the charge spectra and of abundances of the primary cosmic rays with nuclear charge Z>10. It was a passive instrument made of layers of CR39 R and Lexan R /Makrofol R nuclear track detectors; it had a geometric acceptance of ∼0.7 m 2 sr for Fe nuclei. Here, the scanning and analysis strategies, the algorithms used for the off-line filtering and for the tracking in automated mode of the primary cosmic rays are presented, together with the resulting CR charge distribution and their abundances.
