Matrix isolation and cryogenic thin film approaches have been employed for the synthesis, isolation, and characterization of 1:1 and 1:2 complexes of (CH3)2Zn with CH3OH and CH3SH.These complexes were characterized by a shifting of certain sensitive vibrational modes of the acid and base subunits in the complex.The ratio of the 1:1 and 1:2 complexes could be altered by changing the relative amounts of the two reagents employed in a given experiment or by warming the cryogenic thin film from 14 K to as high as 200 K.Merged jet mixtures of (CH3)2Zn with either CH3OH and its isotopomers or CH3SH were also pyrolyzed at temperatures as high as 370 deg C.For the (CH3)2Zn/CH3OH pair, significant production of CH4 and CH2O was observed with minor amounts of C2H4.In the (CH3)2Zn/CH3SH experiments a substantial yield of (CH3)2S and CH4 was obtained.These pyrolytic reactions and products have not been reported previously and may have implications for the chemical vapor deposition of ZnO and ZnS.
