WebJan 1, 2024 · While the synthesis and reactivity of p*Fe(h5-P5)] are well investigated, the corresponding arsenic rivative, pentaarsaferrocene [Cp*Fe(h5-As5)], has far less en studied. This is mainly due to the difficulties in the neration and handling of yellow arsenic As4 as the starting aterial, which is highly light-sensitive and practically cannot ... WebThe reaction can take several seconds to begin, but when it occurs it will be very quick, vigorous, and exothermic. Generally larger sample sizes will react faster than smaller. Likewise, lower average molecular weight materials will react faster than heavier. Do not be mislead by an initial lack of reactivity.
