Rearrangement of silatranyl- and 3,7,10-trimethylsilatranyloxiranes to silatranylaldehydes and the crystal structure of silatranylacetaldehyde
摘要:
Silatranylacetaldehyde N(CH2CH2O)3SiCH2CHO and 3,7,10-trimethylsilatranylacetaldehyde N(CH2CHMeO)3SiCH2CRO were prepared in high yields by rearrangement of the corresponding silatranyloxiranes N(CH2CHRO)3SiCHCH2O(R = H, Me), with triethylbromostannane as a catalyst. An X-ray diffraction study of the parent silatranylacetaldehyde revealed the presence, along with the expected silatranylaldehyde, of some of the starting material silatranyl ethylene. Refinement of an appropriate disorder model for C6H12NO3Si(CH2CHO)0.75(CH=CH2)0.25 led to R/wR = 0.061/0.046.
