Hand in hand with the declining ecological significance of tetraorganolead compounds, the interest in such molecules is also decreasing, and comprises now mostly purely academic aspects. Most results in this field have been summarized in COMC(1982) and COMC(1995), as well as the five volumes of the Gmelin series Organoelement Compounds that appeared between 1987 and 1996.14 18...

Thermal decomposition of Zn(CH3)2 or its co-pyrolysis with other organoelement compounds has been studied mass spectrometrically ". Only two Zn-containing ions ([ZnCH3]+ and [Zn]+) were detected at 100 °C from the co-pyrolysis of an equimolar mixture of f-butyl(allyl)selenium and dimethylzinc " . The relative intensities of the peaks corresponding to the [ZnCH3]+ and [Zn]+ ions diminish as the temperature increases, becoming negligible at T > 320 °C.

Carbon-13 shifts of representative phosphines [364], phosphonium salts [365], phospho-nium ylides [365, 366], diphosphines [367], phosphonates [368], phosphorous and phosphoric acid derivatives [369] are summarized in Table 4.49. I3C shift data of some group V organoelement compounds are compared in Table 4.50. It turns out that a sp3 carbon nuclei of phosphines and arsines are shielded (0-25 ppm) relative to those of amines (30-60 ppm), as expected from the heavy atom effect, sp2 carbons of CC double bonds behave correspondingly, as shown for the triphenyl derivatives in Table 4.50, with...
