Smoked bamboo, which was made by bamboo in high temperature smoke, is a new indoors materials. In order to evaluate its potential health risk to human settlements, the volatile organic compounds of smoked bamboo biomaterial were adsorbed and determined by TD-GC-MS. And the main constituents of volatiles at 60°С were cyclononasiloxane, octadecamethyl-(35.14%), acetic acid(23.27%), cyclotrisiloxane, hexamethyl- (9.53%), bicyclo[4.4.0]dec-1-ene,2-isoprop yl-5-methyl-9-methylene-(7.56%), silane, 1,4-phenylenebis[trimethyl(4.32%), 1,3-benzodioxole, 5-(2-propenyl)- (3.47%), cedrol(2.75%), etc. (2) T

Abstract:
Butatrienone, H2C=C=C=C=O, was generated by pyrolysis of each of six different precursors in a stream of argon at temperatures in the range 710-880°C, and the pyrolysate-argon mixture was condensed on a Csl plate at c. 10 K. Infrared spectra were obtained between 4000 and 250 cm-1. Two precursors, buta-2,3-dienoic trifluoracetic anhydride (1) and buta-2,3-dienoyl chloride (2), gave pyrolysates showing a spectrum consisting of six strong bands and five weak bands.

Abstract:
The 2-pyrrolidino-1,3-dienes (E)-5 and (Z)-5 are obtained by the reaction of lithium di(tertbutyl) cuprate with propyne iminium salt 3. Quantitative Z→E isomerization of 5 takes place within 4 hours at 20 °C. In benzene solution, (E)-5 slowly equilibrates with a [1,5]-H shift to form the 1-amino-1,3-diene derivative 6. In concentrated chloroform solution, however, (E)-5 is transformed into the 3-pyrrolidino-bicyclo[4.2.0]octa-2,4-diene 7 which is identified by X-ray crystal structure analysis. A mechanism for this transformation is proposed.
