Cyclopropyl methyl
Due to the unfavoured bond angles (60°), cyclopropyl groups are highly strained. Two orbital models were proposed to describe the bonding situation. The Coulson-Moffit model uses bent bonds. The C-C bonds are formed by overlap of two sp-hybrid orbitals. To adapt to the small bond angle, there is some rehybridization resulting in sp -hybrids for the ring bonds and sp for the C-H bonds. This model resembles the banana bond model for C=C double bonds (τ bonds). WebNov 12, 1996 · The methoxymycolate series has a methoxy group adjacent to a methyl branch, in addition to a cyclopropane in the proximal position. Using the gene for the enzyme that introduces the distal cyclopropane (cma1) as a probe, we have cloned and sequenced a cluster of genes coding for four highly homologous methyl transferases …
