to V 2 S 3 . Demetallisation of the phthalocyanine (and porphyrin) complexes is more difficult. With H 2 S and thiols, in the presence of nitrogen bases, the VO(phthalocyanine) was reduced with loss of terminal oxygen but without sulphur insertion. With Triethylaluminium, the vanadium was reduced and the phthalocyanine ring system was attacked. The VO(phthalocyanine) catalysed the aerial oxidation of
摘要综述了部分石油中钒化合物的性质。提出了氧杂钒(IV)酞菁和氧杂钒(IV)Schiff碱配合物作为卟啉和沥青质中钒配位的模型。描述了这些化合物与硫化氢,硫醇和其他有机硫化合物,二氧化硫和三乙基铝的反应。席夫碱络合物易于脱金属,钒被转化为V 2 S 3。酞菁(和卟啉)配合物的脱金属更困难。在存在氮碱的情况下,使用H 2 S和硫醇可以还原VO(酞菁),同时减少末端氧,但不会插入硫。用三乙基铝还原钒,并侵蚀酞菁环系统。VO(酞菁)催化H 2 S,硫醇和SO 2的空中氧化。该结果与催化脱金属问题有关。

The using of smaller cryptand[2,2,1](Na+) cations in 5, instead of larger cryptand[2,2,2](Na+) cations in 4, allows one to obtain more closely packed Pc layers.
