Diamond was soldered to a molybdenum plate using a semisolid solder of Zn–15Al and ultrasonic vibration at brazing temperatures not exceeding 900 K. The joint interface was formed by a 10% aluminum solid phase in a semisolid solder when an ultrason

Bicycloporphyrins (CPs) are important compounds as soluble precursors of tetrabenzoporphyrins (BPs). CPs can be converted to the corresponding BPs via selective bromination to meso-position, coupling reaction, and retro Diels–Alder reaction.

We report a new synthesis of 1,4-dihydro-1,4-ethanonaphthalene using 4,9-dihydro-4,9-ethano-2H-benz[f]isoindole as the equivalent of benz[f]isoindole, from p-benzoquinone as a starting material via the Diels–Alder reaction, Luche reduction, and deh

We report the efficient synthesis of tetrabicycloporphyrin platinum under mild conditions (60 °C). The platinum complexes were heated under vacuum to give π-extended platinum porphyrins in 100% yield. The porphyrins are expected to have interesting

We report the efficient synthesis of tetrabicycloporphyrin titanyl and vanadyl without decomposition of the bicyclo[2.2.2]octadiene unit. The complexes were heated under vacuum to give titanyl and vanadyl tetrabenzoporphyrins in 100% yield. We also t
